Question

A shopkeeper bought some lunch bags at 25 per bag and vegetable bags at 35 per bag in the ratio of 7:6. He sold them at a profit of 20% and 30%, respectively. He earned a profit of *392 after selling all the bags. Find the number of lunch bags bought.​

Answer 1

Answer:

28

Step-by-step explanation:

from ratio let the no. of lunch bags be 7x and vegetable bags be 6x;

∴ price of luch bags is 7x × 25 and that of vegetable bags is 6x × 35,

20% of (7x × 25)=35x

30% of (6x × 35)= 63x

35x + 63x = 392 [from the question]

∴ x=4

and lunch bags= 7x= 7×4= 28
