Look at the 6 boxes (3 yellow, 3 pink) on the far right, they represented 2/5 of the original sum of money.

Likewise, the 6 coloured boxes in the middle represented another 2/5 of the original sum.

Thus, the remaining (books + 2 boxes) represented 5/5 – 2/5 – 2/5 = 1/5 of the original sum of money.

crayons ——- 40u

2/5 of her original sum of money ——- 30u

1/5 of her original sum of money ——- 30u/2 = 15u

5/5 of her original sum of money ——- 5 x 15u = 75u

books ——- 75u – 40u – 30u = 5u

40u – 5u = 35u ——- 28

1u 28/35 = 0.8

30u ——- 30 x 0.8 = 24

Ans : $24.
