Options- A. 5/12
- B. 7/12
- C. 1/2
- D. 7
- Correct Answer
- 5/12
Explanation? 7/4 + 5/2 + 67/12 + 10 + 9/4 = (21 + 30 + 67 + 40 + 27/12) = 185/12
This is nearly greater than 15. Let required fraction be x.
Then, 185/12 - x = 15
? x = (185/12) - 15

Correct Answer: 1% loss
Explanation:
Loss%= (common gain or loss % / 10)2 = (10/10)² % = 1%.
Correct Answer: 6.3 yrs
Explanation:
P = Rs. 900, R = 3 ½ % = 7/2 %, T = 2 years.
Therefore,
S.I. = PTR/100
S.I. = Rs. (900 x 7/2 x 2/100) = Rs. 63
Now, P = Rs. 200, S.I. = Rs. 63, R = 5 %
Time = ((100 x 63) / (200 x 5) ) years = 6.3 years.
Correct Answer: x2y2 (x2+ y2+3)=1
Correct Answer: 16000
