If A exceeds B by 40%, B is less than C by20%, then A : C is :
A. 28:25
B. 26:25
C. 3:2
D. 3:1
Solution(By Examveda Team)
Given,
A = B + 40% of B
A = 140/100 * B
Now,
A/B = 14/10
B = C - 20% of C
B = 80/100 *C
B/C = 8/10
SO,
A/C = (A/B) * (B/C) = (14 *8) / (10 *10) = 28 : 25.

A= B + 40% of B = 140/100 * B
So, A/B = 140/100
Again, B = C - 20% of C = 80/100 of C
So, B/C = 80/100
Therefore, A:C = A/B * B/C = 140/100 * 80/100 = 28:25
