Question

A four metre elastic band is increased by 10% find its new length

Answer 1

four metre elastic band increased ,=10%
10%=4*10/100
10%=0.4
length=4+0.4
length=4.4m

Answer 2

Original Length = 4 m
% of length increased = 10%
Therefore Length increased = 10% of 4 m
                                             = 10/100 x 4
                                             = 1/10 x 4
                                             = 4/10
                                             = 0.4 m

Therefore , New Length = Original length + Increased Length
                                       = 4 + 0.4
                                       = 4.4m

Therefore New Length of the elastic band is 4.4 m
