Question

A 4 metre elastic band increased by 10% find new line

Answer 1

hey friend
10% of 4 is equal to 0.4
so the new line will be 4+0.4
=4.4

Answer 2

length of a wire=4m
now, 10 percent of 4m is 4×10/100=0.4
new wire = length of original wire + 10 percent of wire
length of new wire= 4+0.4= 4.4 Ans.
