Detailed Text Solution

Given:

A can do 50% (1/2) of the work in 16 days
B can do 1/4 of the work in 24 days

Step 1: Find total time of A
A does 1/2 work in 16 days
So, full work = 16 × 2 = 32 days

Efficiency of A = 1/32 work per day

Step 2: Find total time of B
B does 1/4 work in 24 days
So, full work = 24 × 4 = 96 days

Efficiency of B = 1/96 work per day

Step 3: Combined efficiency of A and B

A + B = 1/32 + 1/96

LCM of 32 and 96 = 96

= (3 + 1) / 96
= 4 / 96
= 1 / 24

Step 4: Time taken together

Time = 24 days

Final Answer:
A and B together will complete the work in **24 days**
