Among the employees who were engaged in complex and medium operations, the number of employees whose average earning per day in complex operations is more than average earning per day in medium operations is



A 2
B 3
C 5
D 7

Ans. C

If you know Vedic Mathematics, you can easily compare the fraction in time. Thus, employee number 1, 58, 64, 71, 72 satisfy the condition.

(For example: 64, you see 12 is not the double of 5 and 735 is also not even double of 402.)

Hence, 402/5 > 735/12, C.
