# What will be the Reduced Price on Item per Kg? If

A reduction of 21% in the price of an item enable a person to buy 3 kg more for ₹ 100. The reduced price of item per kg is

- ₹ 5.50
- ₹ 7.50
- ₹ 10.50
- ₹ 7.00

**Answer: (4) Rs.7**

**Explanation:-**

Let be the original price = Rs.X per Kg.

Reduced price = 79X/100 per Kg

100 x 100 /79X – 100/X = 3

10000/79X – 100/X = 3

(10000 – 7900 ) /79X = 3

2100 = 3 x 79X

X = 2100/3 x 79

X = Rs.8.86 per kg.

So, Reduced price = .79 x 8.86 = Rs.7 / kg.

Hence, the answer is (4) 7.
