Answers

1: Option B
Explanation:This is a simple division series; each number is one-half of the previous number.
In other terms to say, the number is divided by 2 successively to get the next result.

4/2 = 2
2/2 = 1
1/2 = 1/2
(1/2)/2 = 1/4
(1/4)/2 = 1/8 and so on.

2. Option B

Explanation:
This is a simple alternating addition and subtraction series. In the first pattern, 3 is added; in the second, 2 is subtracted.

3.: Option B
Explanation:
This is an alternating number subtraction series. First, 2 is subtracted, then 4, then 2, and so on.

4.: Option C
Explanation:
In this simple alternating subtraction and addition series; 1 is subtracted, then 2 is added, and so on.

5.: Option B
Explanation:
In this series, each number is repeated, then 13 is subtracted to arrive at the next number.

6. Option B
Explanation:
In this alternating repetition series, the random number 21 is interpolated every other number into an otherwise simple addition series that increases by 2, beginning with the number 9.

7.: Option B
Explanation:
This is a simple subtraction series. Each number is 6 less than the previous number.

8. Option D
Explanation:
This alternating addition series begins with 3; then 1 is added to give 4; then 3 is added to give 7; then 1 is added, and so on.

9.Option D
Explanation:
This is a simple addition series with a random number, 8, interpolated as every other number. In the series, 6 is added to each number except 8, to arrive at the next number.

10.Option A
Explanation:
This is a simple alternating subtraction series, which subtracts 2, then 5

സംഘ്യകളും തുകയും

2010-05-31T05:16:00.000-07:00

1 മുതല്‍ n വരെയുള്ള തുടര്‍ച്ചയായ എണ്ണല്‍ സംഘ്യകളുടെ തുക n(n+1)/2 ആണ്. ഇവിടെ n എന്നത് അവസാനത്തെ സംഘ്യ ആണ്.

ഉദാ: 1 മുതല്‍ 80 വരെയുള്ള സംഘ്യകളുടെ തുക എന്ത്?

n എന്ന സ്ഥാനത്തെ അവസാന സംഘ്യ ഈ ചോദ്യത്തില്‍ 80 ആണ്.

n(n+1)/2

80(80+1)/2

80*81/2 = 40*81 = 3240

Multiplication

2009-09-13T19:01:00.000-07:00

Multiply by 5: Multiply by 10 and divide by 2.
Multiply by 6: Sometimes multiplying by 3 and then 2 is easy.
Multiply by 9: Multiply by 10 and subtract the orginal number.
Multiply by 12: Multiply by 10 and add twice the original number.
Multiply by 13: Multiply by 3 and add 10 times original number.
Multiply by 14: Multiply by 7 and then multiply by 2
Multiply by 15: Multiply by 10 and add 5 times the original number, as above.
Multiply by 16: You can double four times, if you want to. Or you can multiply by 8 and then by 2.
Multiply by 17: Multiply by 7 and add 10 times original number.
Multiply by 18: Multiply by 20 and subtract twice the original number (which is obvious from the first step).
Multiply by 19: Multiply by 20 and subtract the original number.
Multiply by 24: Multiply by 8 and then multiply by 3.
Multiply by 27: Multiply by 30 and subtract 3 times the original number (which is obvious from the first step).
Multiply by 45: Multiply by 50 and subtract 5 times the original number (which is obvious from the first step).
Multiply by 90: Multiply by 9 (as above) and put a zero on the right.
Multiply by 98: Multiply by 100 and subtract twice the original number.
Multiply by 99: Multiply by 100 and subtract the original number.

റോമന്‍ അക്കങ്ങള്‍

റോമന്‍ സമ്പ്രദായം ഏകദേശം 2,000 വര്‍ഷങ്ങളോളം എല്ലാ രംഗത്തും നിലനിന്നു.V,X,L,C എന്നീ നാല് അക്കങ്ങള്‍ ഓര്‍മിച്ചാല്‍ മറ്റെല്ലാം എളുപ്പം എഴുതാവുന്നതിനാലും III, VII എന്നിവ 3, 7 എന്നിവയെക്കാള്‍ എളുപ്പം ഗ്രഹിക്കാവുന്നതായതിനാലും ഏറെക്കാലം ഈ സമ്പ്രദായം നിലനിന്നു. നിവര്‍ത്തിപ്പിടിച്ച കൈപ്പത്തിയുടെ ആകൃതിയിലുള്ള ചിഹ്നമാണ് V. ഇതുപോലെ രണ്ടെണ്ണമായാല്‍ X എന്നായി; ഇതാണ് പത്ത്; പിന്നീട് L ആയി 50-ന്; ø (തീറ്റാ), പിന്നീട് C 100 നെയും സൂചിപ്പിച്ചു; ø (ഫൈ), പിന്നീട് I അഥവാ M 1,000 വും 10, 50, 100, 1000 എന്നിവയുടെ ചിഹ്നങ്ങള്‍ ക്രമത്തില്‍ പട്ടിക സി-യില്‍ കാണാം.

ബി.സി. 260-ല്‍ റോമാക്കാര്‍ കാര്‍തേജിയന്‍മാരുടെ മേല്‍ നേടിയ വിജയത്തെ അനുസ്മരിച്ച് സ്ഥാപിക്കപ്പെട്ട സ്തംഭത്തിന്‍മേല്‍ (Columna Rostrata) കാണുന്ന അക്കങ്ങളാണ് വലിയ സംഖ്യകളുടെ ഏറ്റവും പ്രാചീനമായ രേഖകള്‍. ഇതില്‍ (((1))) എന്നിങ്ങനെ 23 പ്രാവശ്യം ആവര്‍ത്തിച്ചു കാണുന്നത് 23,00,000 ആണ്.

ഇതില്‍നിന്ന് (1) = 1,000, ((1)) = 10,000, (((1))) = 1,00,000 എന്ന് ഊഹിക്കാം. അച്ചടി സാധാരണമായതിനുശേഷവും ഈ സമ്പ്രദായം നിലനിന്നു. ചിഹ്നത്തിന്റെ മുകളില്‍ ഒരു വരയിട്ട് 1,000 ത്തിന്റെ പെരുക്കത്തെ സൂചിപ്പിക്കുന്ന സമ്പ്രദായം മധ്യകാലത്തു പ്രചാരത്തിലിരുന്നു. ഈ രീതി റോമില്‍ ഉണ്ടായിരുന്നില്ല. കുറച്ചെഴുതുന്ന സമ്പ്രദായം ഹീബ്രുവിലും ചില റോമന്‍ അക്കങ്ങളിലുമുണ്ട്. IV, IX എന്നിവ ഉദാഹരണങ്ങളാണ്. ഗുണിച്ചെഴുതി ഗ്രൂപ്പു ചെയ്യുന്ന സമ്പ്രദായം ചൈനയിലുണ്ടായിരുന്നു. സ്ഥാനമനുസരിച്ചുള്ള എഴുത്താണ് ആധുനിക ചൈനയില്‍ നിലവിലുള്ളത്. പൂജ്യത്തെ o എന്ന വൃത്തചിഹ്നംകൊണ്ടാണ് സൂചിപ്പിക്കുന്നത്.
