A. 1/13
B. 2/13
C. 1/26

A. 68 4/7 %
B. 78 %
C. 80 %
D. 80 4/7 %
Explanation:
Total candidates = (100 + 75) = 175
Total passed = (75/100 × 100) + (60/100 × 75)
= (75 + 45) = 120
Therefore Pass % = (120/175 × 100)%
= 480/7 % = 68 4/7 %
A. 120 cm2
B. 130 cm2
C. 312 cm2
D. 315 cm2

C. 69/28
D. 66/17
Explanation:
(22 * 495 + 891 * 44) / (33 * 176 + 55 * 264) = (22 * 33 * 15 + 9 * 99 * 2 * 22) / (33 * 22 * 8 + 5 * 11 * 22 * 12)
= (22 * 33 * 15 + 22 * 33 * 54) / (33 * 22 * 8 + 33 * 22 * 20) = [22 * 33(15 + 54)] / [33 * 22(8 + 20)] = 69/28
A. 3 1/4 min
B. 5 1/4 min
C. 8 1/4 min
D. 9 1/4 min
Explanation:
3/12 + (3 + x)/15 = 1

A. Rs. 1505
B. Rs. 1510
C. Rs. 1500
D. Rs. 1490
E. None of these
Explanation:
Let the cost price of an article be Rs. x.
(19% of x) – (12% of x) = 105
19x/100 – 12x/100 = 105 => 7x = 105 * 100
=> x = 1500
Cost price = Rs. 1500
