Question

if 42 man reap a field in 16 days. in how many days can 56men reap the same field? ​

Answer 1

Step-by-step explanation:

M1×D1= M2×D2

42×16 = 52× D2

D2 = 672/52

D2 = around 12 days

Answer 2

Given:-

M1 = 42

D1 = 16

M2 = 56

D2 = x

According to chain rule

M1 × D1 = M2 × D2

$42 \times 16 = 56 \times x \\ \\( 42 \times 16 ) \div 56 = x \\ \\ \frac{672}{56 } = x \\ \\ 12 = x \\ \\ therefore \\ \\ x = 12 \: days.$
