- Question
- The area of a rectangle is thrice that of square. Length of the rectangle is 40 cm and the breadth of the rectangle is ( 3 / 2 ) times that of the side of the square. The side of the square in cm is?
Options- A. 15
- B. 20
- C. 30
- D. 60
- Correct Answer
- 20
ExplanationLet the side of the square = y cm
Then, breadth of the rectangle = 3y/2 cm
? Area of rectangle = (40 x 3y/2) cm2
= 60y cm2
? 60y = 3y2
? y = 20
Hence, the side of the square = 20 cm - 1. A man is watching from the top of a tower a boat speeding away from the tower.

Correct Answer: 2704
Explanation:
| Given Exp. | = [(a + b)2 - 4ab], where a = 476 and b = 424 |
| = [(476 + 424)2 - 4 x 476 x 424] | |
| = [(900)2 - 807296] | |
| = 810000 - 807296 | |
| = 2704. |
Correct Answer: 210
Explanation:
Let the number be P.
According to the question,
P - P/7 = 180
? 6P/7 = 180
? P = 180 x 7/6 = 210
Correct Answer: ?ab
Explanation:
Correct Answer: 140
Explanation:
20 x x = (64 + 36)(64 - 36) = 100 x 28
| ⟹ x = | 100 x 28 | = 140 |
| 20 |
Correct Answer: 5336
Explanation:
Divisor = 5 x 46 = 230
Also, 10 x Quotient = 230
? Quotient = 23
We know that
Dividend = (Divisor x Quotient ) + Remainder
? Dividend = (230 x 23) + 46
? Dividend = 5290 + 46 = 5336
Correct Answer: Rs. 432
Explanation:
Correct Answer: 8
Explanation:
( x n - 1) will be divisibly by ( x + 1) only when n is even.
(4915 - 1) = {(72)15 - 1} = (730 - 1), which is divisible by (7 +1), i.e., 8.
Correct Answer: 48
Explanation:
Let be the ten's digit be P and unit's digit be Q.
The two-digit number = 10P + Q
(where, P > Q)
According to the question,
P + Q = 14 ......(i)
and P - Q = 2 .......(ii)
solving Eqs. (i) and (ii), we get
P = 8 and Q = 6
? Required product = 8 x 6 = 48
Correct Answer: 15 / 11
Explanation:
Given expression = (7 + 7 + 7 ÷ 7) / (5 + 5 + 5 ÷ 5)
= (14 + 1) / (10 + 1)
=15 / 11
