Question

Mr Joshi bought 512 potatoes at rupees 200 per quintal and paid a total cartage of rupees 40.50. he sold these at rupees 230.25 per quintal. Find his profit.​

Answer 1

If C.P. of 1quintal =rs.200

Then C.P. of 5quintal = rs.200×5=rs.1000

Cartage paid =rs.1000+40.50=1040.5

S.P. of 5 quintal potatoes =5×230.25=1151.25

Profit =1151.25-1040.5 = rs.110.75

Answer 2

Answer:

Let us suppose the cost of 12 kg onions is x rupees.

The number of onions and their cost vary in direct proportion.

∴7140=12x⇒x=12×1407

= 240 rupees

Hence, the cost of 12 kg onions is 240 rupees.
