- Question
- If 0.764 B = 1.236 A, then what is the value of (B - A)/(B + A)?
Options- A. 0.764
- B. 0.236
- C. 2
- D. 0.472
- Correct Answer
- 0.236
ExplanationGiven, 0.764 B = 1.236 A
? B/A = 1.236 / 0.764
Now, (B - A)/(B + A) = (B/A - 1) / (B/A + 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: 256
Explanation:
(?)1/2 = (5568 / 87)1/3 + (72 x 2)1/2
= (64)1/3 + (144)1/2
? ? = (4 + 12)2 = 256
Correct Answer: 711/12
Explanation:
? = 32/3 + 23/4 + 11/2
= 3 + 2 + 1 + (2/3 + 3/4 + 1/2)
= 6 + (8 + 9 + 6)/12 = 6 + (23/12)
= 6 + (111/12)
= 711/12
Correct Answer: 7 / 30
Explanation:
Given Exp. = [(4 x 5 x 6) + (5 x 6) + (2 x 6) + (2 x 3)] / [(2 x 3 x 4 x 5 x 6)]
= 168 / (24 x 30)
= 7 / 30
Correct Answer: 161 / 176
Explanation:
Given Exp. = (1/2 x 1/4 + 20) / (2 + 20) = (161/8) x (1/22)
= 161 / 176
Correct Answer:
Explanation:
7059 - 2350 + 1936 = ? x 50
? 8995 - 2350 = ? x 50
? ? = 6645/50 = 132.9
Correct Answer: 757704
Explanation:
Required number
= 786 x 964 = 757704
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: 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: 4
Explanation:
(?)2 ?132 + 28 ÷ 4 - (3)3 + 107
= ?169 + 7 - 27 + 107
= ?256 = 16
? ? = ?16
= 4
