S buys sugar for Rs 40 per kg and sells at Rs x per kg. Due to a fault in the weighing machine, it shows 1 kg when the actual eight is 800 gm. What is the value of x per kg if his profit percentage is 30%?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 41.6.
The cost price of the sugar of 1 kg = Rs 40
Selling price of the sugar = Rs x per kg
For selling he uses false weight 800 gm instead of 1kg
So, the cost price of the 800 gm sugar = 40/1000 × 800 = Rs 32
He got 30% profit
SP = x = 32 × (100 + 30)/100 = Rs 41.6
