x is 10% greater than n
let n=10; then x=11 (10% of 10+10)
y is 30% greater than m
let m=20; then y=26(30% of 20+20)
then
xy=286
mn=200
now the ques becomes 286 is what percent greater than 200;
[(286-200)/200] x 100 = 43%
let n=10; then x=11 (10% of 10+10)
y is 30% greater than m
let m=20; then y=26(30% of 20+20)
then
xy=286
mn=200
now the ques becomes 286 is what percent greater than 200;
[(286-200)/200] x 100 = 43%
