Answer: Option D

Amount = P(1 + R/100)^n
Where Principal = P, Rate = R% per annum, Time = n years.
12100 = 10000 (1+R/100)^2
=> 121/100 = (1+R/100)^2
=> 11/10 = (1+R/100)=> 11/10 = (100 + R)/100
=> 110 = 100 + R => R = 10%

Answer: Option D

1992 is a leap year because it is divisible of 4
A leap year consists of 366 days i.e, 52 weeks + 2 odd days
from 1st jan to 24th oct we have 297 days

69 days i.e, 9 weeks + 6 odd days
i.e 6 odd days means SATURDAY
As 0 odd days is sun, 1 odd day is mon, 2=tue, 3=wed,4=th,5=fri, 6 odd days is sat.

Answer: Option A

Lets assume daughter's present age = x Years.
So, Father's present age = (5/2)*x Years.
5 years ago father's age = (5x/2)-5 = 3(x-5) Years.
Therefore,x=20 years

Answer: Option C

case 1: degree=(11/2)(min) -30(hr) 90=(11/2)(min) - 30*7
min= 54(6/11) past 7 0 'clock

case2: 60/55 *20
as it is 20 min apart
solving we get 21 (9/11) min past 7' 'O clock

Answer: Option B

9+x = 23-x 2x = 14
X = 7
Now 9+x = 16

Answer: Option C

Given A=20,000
B=10,000
C=40,000
so their ration = 20,000 : 10,000 : 40,000 = 2:1:4
Given profit = 14000
A share = 4000, B share = 2000, C sahre = 8000

Answer: Option A

10% interest per annum will be 5% interest half yearly for 3 terms( 1 1/2 years)
So compound interest = 3000[1+(5/100)]^3 - 3000
= 3000[(21/20)^3 -1]
= 3000(9261-8000)/8000
= 3*1261/8
= 472.8 ~ 473
