Question

when a number is increased by 10% it became 880 if 10% of 880 is deducted from it, then how much percent more or less the number would be than the original number?
options :
a) 1%
b) 1% less
c) 1% more
d) No change​

Answer 1

800
10% increase so 880
880
10% decreased 88
So 880-88=792
800-792=8

Answer 2

Answer:

b) 1% less

Step-by-step explanation:

original number= let it be x

ATQ

x+10% of x =880

x+10/100× x=880

11x=88000

x= 8000

So,

8000-10%of 880

8000-10/100×880

= 7912

original number= 8000

new number= 7912

decrease= 8000-7912= 88

decrease %= decrease/original number × 100

= 88/8000×100

=11/10= 1.1%

Hence, the new number is approximately 1% less than the original number.
