Why not. U are confused, here is the short cut.
10%of 450 is 45 then
40%of 450 will be 45*4=180.

We have
(1/4 of 1/3 of 2/5)x of 40%=15
1/30 x of 40%=15
(x/30*100)/40=15
= 180
(1/4 of 1/3 of 2/5)x of 40%=15
1/30 x of 40%=15
(x/30*100)/40=15
= 180

@sonu
the answer is 18
sol:
1/4*1/3*2/5*x=15
we get
x=15*30
x=450
and
40% of 450 means
40/100*450=18
the answer is 18
sol:
1/4*1/3*2/5*x=15
we get
x=15*30
x=450
and
40% of 450 means
40/100*450=18

Answer is wrong because take an example.
x = 10, y = 100 (x is less than y).
Then A = x% of y => 90.
B = y% of x => 10.
So, answer is 'D' not 'E'.
x = 10, y = 100 (x is less than y).
Then A = x% of y => 90.
B = y% of x => 10.
So, answer is 'D' not 'E'.
