kg apples. She gave a ₹500 note to the shopkeeper. How much did she get back ?

Solution:

cost of water melon

=\;{9}/{2} × 18.50=₹ \;83.25

cost of cherry

= \;{6}/{5} × 72= ₹\; 86.40

cost of grapes

= \;{1}/{4} × 120.60=₹\; 30.15

cost of apples

= \;{7}/{4} × 78.40=₹\; 137.20

Total cost = ₹ 83.25 + ₹ 86.40 + ₹ 30.15 + ₹ 137.20
