How much rupees Sonia was having in the beginning? Correct Answer 42
Given:
Money left with sonia at end = Re. 1
Calculations:
Let the total money of Sonia = Rs. 8x
Money given to lady by Sonia for cancer patient
= ((8x)/2 + 1) = Rs. 4x + 1
Money left with Sonia after donating to cancer patient
= (8x - (4x+1)) = 4x -1
Money given to girl by Sonia for poor peoples' fund
= ((4x-1)/2 + 2) = Rs. 2x + 1(1/2)
Money left with Sonia after donating to poor peoples' fund
= ((4x -1) - (2x + 1(1/2))) = Rs. 2x - 2(1/2)
Money given to boy by Sonia for blind's fund
= ((2x - 2(1/2))/2 + 3) = Rs. x + 1(3/4)
Money left with Sonia after donating to blind's fund
= (2x - 2(1/2)) - ( x + 1(3/4)) = x - 4(1/4)
According to question,
⇒ x - 4(1/4) = 1
⇒ x - (17/4) = 1
⇒ x = 1 + (17/4)
⇒ x = (4 + 17)/4
⇒ x = (21)/4
∴ 8x = (21)/4 × 8 = 42
∴ Total money Sonia was having in the beginning is Rs. 42.
