A. 4000
B. 3000
C. 5000
D. 2000
Answer : B. 3000
Explanation 1:
Babla work = 1/10
Ashu work = 1/15
Total work = 1/10 + 1/15
= 5/30
= 6 days.
Total amount to be paid for Babla = 6/10 * 5000
= 3000
Explanation 2:
Money should always be divided in the inversely proportion way.
So Babla will get money = 15 / (15 + 10) × 5000
= 3000
