Question

Find the sum which becomes 19,320 on increasing by 15%.​

Answer 1

Answer:

16800

Step-by-step explanation:

let us take the number as x

such that x + (15x / 100) = 19320

100x + 15x / 100 = 19320

115x = 1932000

x = 16,800

Answer 2

Answer- The required sum is ₹ 16800 which when increased by 15% becomes ₹ 19320.

Solution -

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 = ₹ 16800

Hence, the required sum is ₹ 16800 when increased by 15% becomes ₹ 19320.
