Let’s assume Manoj has Rs. X in total.
Amount required to buy either 60 apples = Amount required to by 80 mangoes = X
Amount spent in buying 28 mangoes $(= X \times \frac{{28}}{{80}} = 0.35X)$
Amount Manoj wants to spend = 40% of X = 0.4X
Remaining amount = 0.4X – 0.35X = 0.05X
Number of apples that can be bought in remaining amount $(= 60 \times \frac{{0.05X}}{X} = 3)$
Amount required to buy either 60 apples = Amount required to by 80 mangoes = X
Amount spent in buying 28 mangoes $(= X \times \frac{{28}}{{80}} = 0.35X)$
Amount Manoj wants to spend = 40% of X = 0.4X
Remaining amount = 0.4X – 0.35X = 0.05X
Number of apples that can be bought in remaining amount $(= 60 \times \frac{{0.05X}}{X} = 3)$
