Question

One-fifth of a number is equal to 3/8 of another number. If 17 is added to the first number, it becomes four times of the second number. What is the second number

Answer 1

Answer:

8

Step-by-step explanation:

let us assume x is first number and y is second number

given

x+17=4y

x=4y-17

given

1/5 of x = 3/8 of y

x/5=3y/8

by substituting x=4y-17

4y-17=15y/8

8(4y-17)=15y

32y-136=15y

32y-15y=136

17y=136

y=136/17

y=8
