When the number is reduced by 15% , the answer is 6154 . What is the original number ?
Vesna [10]

Let's assume the number as x .

15% of x = \dfrac{x \times 15}{100}

→ \dfrac{3x}{20}

So after reducing 15% the number will be 6154 .

→ x - 3x/20 = 6154

→ 17x/20 = 6154

→ 17x = 6154 × 20

→ 17x = 123080

→ x = 123080/17

  • → x = 7240

So the number is 7240
