Question

If a work can finished in 22 days but in the absence of 3 labours a work can finish in 24 days so what is the starting number of labours Options: (a) 24 (b) 36 (c) 32 (d) 40​

Answer 1

Answer:

(b) 36

Step-by-step explanation:

The number of labours and the time taken to finish the work are inversely proportional. If two quantities are inversely proportional, their product remains constant.

Let the number of labours be x.

=> 22 × x = 24 × (x-3)

=> 22x = 24x-72

=> 72 = 24x - 22x

=> 72 = 2x

=> x = 72/2

=> x = 36
