Question:The rate percent is:
[A].11% [B].
10% [C].
5% [D].
5.5% Answer: Option C
Explanation:
Let T.D. be Re. 1.
Then, B.D. = Rs. 11 = Rs. 1.10. 10 Sum = Rs. 1.10 x 1 = Rs. 110 = Rs. 11. 1.10 – 1 10 S.I. on Rs. 11 for 2 years is Rs. 1.10
Rate = 100 x 1.10 % = 5%. 11 x 2 Which of the following number is divisible by 24 ?
Question: Which of the following number is divisible by 24 ?
[A].35718 [B].
63810 [C].
537804 [D].
3125736 Answer: Option D
Explanation:
24 = 3 x8, where 3 and 8 co-prime.
Clearly, 35718 is not divisible by 8, as 718 is not divisible by 8.
Similarly, 63810 is not divisible by 8 and 537804 is not divisible by 8.
Consider option (D),
Sum of digits = (3 + 1 + 2 + 5 + 7 + 3 + 6) = 27, which is divisible by 3.
Also, 736 is divisible by 8.
3125736 is divisible by (3 x 8), i.e., 24.
The difference of two numbers is 1365. On dividing the larger number by the smaller, we get 6 as quotient and the 15 as remainder. What is the smaller number ?
Question:
The difference of two numbers is 1365. On dividing the larger number by the smaller, we get 6 as quotient and the 15 as remainder. What is the smaller number ?
[A].240 [B].
270 [C].
295 [D].
360 Answer: Option B
Explanation:
Let the smaller number be x. Then larger number = (x + 1365).
x + 1365 = 6x + 15
5x = 1350
x = 270
Smaller number = 270.

Hafeez invested Rs. 15000 @ 10% per annum for one year. If the interest is compounded half-yearly, then the amount received by Hafeez at the end of the year will be?A. Rs. 16,500
B. Rs. 16,525.50
C. Rs. 16,537.50
D. Rs. 18,150
Explanation:
P = Rs. 15000; R = 10% p.a. = 5% per half-year; T = 1 year = 2 half-year
Amount = [15000 * (1 + 5/100)2]
= (15000 * 21/20 * 21/20) = Rs. 16537.50Which of the following is equal to 3.14 x 106 ?
