Question

find the sum which becomes 19320 on increasing by 15%

Answer 1

Answer:

Step-by-step explanation:

Let the sum be ₹ x

Then, according to the question.

x/1 + (x × 15)/100 = ₹19320

x/1+15x/100 = ₹19320

x/1 + 3x/20 = ₹19320

LCM of 20 &1 is 20

(20x + 3x)/20 =19320

23x/20 = 19320

23x = 19320 × 20

23x = 3864000

X = 386400/23

X = ₹ 1680

Answer 2

let the no. be x
increase %=15

ATP
x+15%=19320
=)115x/100=19320
=)x=(19320*100)/115
=)x=1680

Therefore, the sum is 1680
