• 14 days
• 12 days
• 8 days
• 10 days

Answer 1

সঠিক উত্তর হচ্ছে: 10 days

ব্যাখ্যা:

Ratio of efficiencies of Priya and Sai is

Sai : Priya = 160 : 100 = 8 : 5

Given Priya completes the work in 16 days

Let number of days Sai completes the work be 'd'

=> 5×16 = 8×d

d = 10 days.

Therefore, number of days Sai completes the work is 10 days.
