When 70% of a number x is added to another number y, the sum becomes 165% of the value of y. When 60% of the number x is added to another number z, then the sum becomes 165% of the value of z. Which one of the following is correct?
When 70% of a number x is added to another number y, the sum becomes 165% of the value of y. When 60% of the number x is added to another number z, then the sum becomes 165% of the value of z. Which one of the following is correct? Correct Answer z < x < y
Calculation:
Let there are three numbers x, y and z.
70% x + y = 165% y
70x + 100y = 165y
70x = 65y
14x = 13y
x/y = 13/14
60% x + z = 165% z
60x + 100z = 165z
60x = 65z
12x = 13z
x/z = 13/12
So, we get x = 13, y = 14, z = 12.
y > x > z
Hence, option 1 is correct.
