30 men working 16 hours per day construct a school in 20 days.In how many days with 24 working 20 hours per day do it
Answers
Answer:
20 days
Step-by-step explanation:
Given that,
No. of men working = 30
No. of hours working = 16
No. of days required = 20
∴ total no. of hours required to construct the school by 30 men = 16 × 20 = 320
So,
Amt. of time required for 30 men = 320 hrs
Amt. of time required for 1 men = 320 * 30
Amt. of time required for 24 men = 320 * 30/24 = 400
Given that,
24 men are working 20 hours per day
Total hrs required for 24 men = 400
Hence, no. of days
= (total no.of hrs) ÷ (no. of days required)
= 400/20
=20
Hence, In 20 days the 24 men working 20 hrs per day can finish the construction of school (ANS.)

Given that,

No. of hours working = 16

Amt. of time required for 1 men = 320 * 30
Amt. of time required for 24 men = 320 * 30/24 = 400
Given that,
24 men are working 20 hours per day
Total hrs required for 24 men = 400
Hence, no. of days
= (total no.of hrs) ÷ (no. of days required)
= 400/20
=20
Hence, In 20 days the 24 men working 20 hrs per day can finish the construction of school
