Detailed Solution for Quantitative Aptitude - Test 14 - Question 3

A : B = 2 : 3

B : C = 4 : 5

A : B : C = 8 : 12 : 15

amount received by A = 8/(8 + 12 + 15) * 700 = 160/-

amount received by B = 12/(8 + 12 + 15) * 700 = 240/-

amount received by C = 15/(8 + 12 + 15) * 700 = 300/-

so the answer is option B.

A and B together can do a works in 12 days. B and C together do it in 15 days. If A's efficiency is twice that of C, then the days required for B alone to finish the work is

Detailed Solution for Quantitative Aptitude - Test 14 - Question 7

A and B will do in 1 day, 1/12​ amount of work
B and C will do in 1 day, 1/15​ amount of work
Hence adding up above two equations
A + 2B + C will do in 1 day, 9/60 amount of work
as it is mentioned A = 2C (i.e. efficiency of A is twice of C)
So 2C + 2B + C will do in 1 day 9/60 amount of work
or 2(B+C) + C = 9/60
or C = 1/60​ (as B + C = 1/15) So B alone will do work in 20 days.
