- Question
- If 0.764 x P = 1.236 x Q, then what is the value of (Q - P) / (Q + P)?
Options- A. 0.764
- B. 0.236
- C. 2
- D. 0.472
- Correct Answer
- 0.236
ExplanationGiven, 0.764 x P = 1.236 x Q
? Q / P = 1.236 / 0.764
Now, (Q - P) / (Q + P) = [(Q/P) - 1] / [(Q/P) + 1]
? [(1.236/0.764) - 1] / [(1.236/0.764) + 1]
= (1.236 - 0.764) / (1.236 + 0.764)
= 0.472 / 2.000
= 0.236 - 1. ? 289 - ? 625 ÷ ? 25 is equal to?

Correct Answer: 12
Explanation:
?289 - ?625 ÷ ?25
= ?17 x 17 - ?25 x 25 ÷ ?5 x 5
= 17 - 25 ÷ 5 = 17 - 5 = 12
Correct Answer: 4
Explanation:
(?)2 ?132 + 28 ÷ 4 - (3)3 + 107
= ?169 + 7 - 27 + 107
= ?256 = 16
? ? = ?16
= 4
Correct Answer: 17
Explanation:
(4 x 4 x 4 x 4 x 4 x 4)5 x (4 x 4 x 4)8 ÷ (4)3 = (64)?
? (46)5 x (43)8 x 1/(4)3 = (43)?
? (4)30 x (4)24/(4)3 = (4)3 x ?
? 430 + 24 - 3 = 43 x ?
? 451 = 43 x ? ? 3 x ? = 51
? ? = 51/3 = 17
Correct Answer: 321/32
Explanation:
? = 5/8 x 23/5 ÷ 4/9
= 5/8 x 13/5 x 9/4 = 117/32 = 321/32
Correct Answer: 757704
Explanation:
Required number
= 786 x 964 = 757704
Correct Answer: 40 m
Explanation:
Required length = 120/3 = 40 m
Correct Answer: 17
Explanation:
Let the number = a
According to the question,
a x 5a = 1445
5a2 = 1445
? a2= 1445/5 =289
? a= ?289 = 17
Correct Answer: 20 inches
Explanation:
Required length = 80/4 = 20 inches
Correct Answer: 19
Explanation:
Since a * b = a + b + a/b
? 12 * 4 = 12 + 4 + 12/4
= 12 + 4 + 3 = 19
Correct Answer: 1/4
Explanation:
Given exp. = [ a2 + ab + b2 ] / [a3 - b3] where a = 137, b = 133
= 1/(a - b)
= 1/(137- 133)
=1/4
