Answer 1

sorry iam answering like this for points

Answer 2

Aηѕωєя :-❤A) 20 hours

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
