Problem Solving: Work and Rate Problems Practice MCQ

Question Statement:

A alone can complete a work in 16 days and B alone can do in 12 days. Starting with A, they work on alternate days. The total work will be completed in

op a Dup 3 -18988392
op b Dup 3 -99628040
op c Dup 3 -87941456
op d Dup 3 -21350744

Explanation:

Correct Answer: C

A's 1 day work = 1/16

B's 1 day work = 1/12

As they are working on alternate day's

So their 2 days work = (1/16)+(1/12)

= 7/48

[here is a small technique, Total work done will be 1, right, then multiply numerator till denominator, as 7×6 = 42, 7×7 = 49, as 7×7 is more than 48, so we will consider 7×6, means 6 pairs ]

Work done in 6 pairs = 6×(7/48) = 7/8

Remaining work = 1-7/8 = 1/8

On 13th day it will A turn,

then remaining work = (1/8)-(1/16) = 1/16

On 14th day it is B turn,

1/12 work done by B in 1 day

1/16 work will be done in (12×1/16) = 3/4 day

So total days =

op c Dup 4 -87344472

It may be a bit typical question, but if are not getting it in first try then give it a second try. Even not, then comment
