Question

Minu bought a cake and left it on the table in the morning. When she came home in the evening, she saw that 2/5 of the cake had been eaten. She ate 1/3 of the remaining cake. Her brother ate 1/5 of the remaining cake. Find the portion of the remaining cake left.

Answer 1

Heya......

______________________

The whole cake = 1

Eaten part = 2/5

Left cake = 1/1 -2/5

 = 3/5 (LCM OF 1 & 5)

She ate 1/3

= 3/5 - 1/3

9/15 -5/15

4/15 Left cake after She ate

Her Brother ate 1/5 

= 4/15-2/5

4/15 - 6/15


Since, This is not possible as he can't eat cake in Negative....

This Means the whole cake was eaten..
