Options

A. 40
B. 25
C. 35
D. 30

Answer

C

Explanation

Asha saves on Monday = ₹ 50
Asha saves on Wednesday = ₹ 100
Asha saves on Friday = ₹ 80
Total saved till now
= 50 + 100 + 80 = ₹ 230
Asha spend on Sunday =₹ 60
Whole week saving = ₹ (230 - 60) = ₹170
Every week Asha saves ₹ 170.
Let it takes .x. weeks for Asha to collect ₹ 5950.
Now, week `xx` every week saving = 5950
`x xx 170= 5950 `
`x = (5950)/(170)`
x= 35
It takes 35 weeks for Asha to collect ₹ 5950.
