Answer:

sorry I cant understamd question 1

Answer 2

Concept:

Unitary method is a method to compare the two numbers in their unit value.

Given:

We are given that:

Sania can finish a work in 17 days.

Mirza can do it in 85 days.

Mirza left job after 10 days.

Find:

We need to find the number of days that Sania will take to complete the remaining work.

Solution:

Let the total work be 1.

Work done by Mirza in one day = 1 / 85.

Work done by Mirza in 10 days = 10 / 85 = 2 / 17

Work left = 1 - 2 / 17

= 15 / 17

Work done by Sania in 1 day = 1 / 17

Number of days that Sania can complete work = 15 / 17 ÷ 1 / 17 = 15 days.

Therefore, Sania will take 15 days to complete the remaining work.
