Question

In a furniture shop, 24 tables were bought at the rate of ₹ 450 per table. The shopkeeper sold 16 of them at the rate of ₹ 600 per table and the remaining at the rate of 400 per table. Find her gain or loss percent.

Sum

Solution

As per the given information in question,

Cost Price (C.P.) of per table = ₹ 450

Number of tables = 24

So, cost price of 24 tables = 24 × 450 = ₹ 10800 

Since, 16 tables sold at the rate of ₹ 600.

∴ Selling price of 16 tables = 16 × 600 = ₹ 9600

∴ Remaining tables = 24 – 16 = 8

Since, 8 tables sold at the rate of ₹ 400.

Selling price (S.P.) for 8 tables = 8 × 400 = ₹ 3200

Total selling price = 9600 + 3200 = ₹ 12800

∴ Profit or gain = S.P. – C.P.

= 12800 – 10800

= ₹ 2000

Now, gain = `"Gain"/"Cost price" xx 100%`

= `2000/10800 xx 100%`

= `2000/108%`

= 18.51%

Hence, her gain is 18.51%.
