Question

The number 2400 is first increased by 30%. The value obtained is
next decreased by 20%. Find the final number

Answer 1

Answer:2496

Step-by-step explanation:First we need to find 30% of 2400.

So, (2400*30)÷100 = 720

Increase by 30% = 2400+720= 3120

Now,

Decrease by 20%

(3120*20)÷100 = 624

Therefore final number = 3120-624= 2496

Hope it helps!!!

Answer 2

1st increase by 30%.
2400×30÷100= 720.
2400+720= 3120

2nd decrease by 20%
3120×20÷100=624
3120-624=2496.

Therefore,the final no. is 2496.
