80/100*x+90/100*x-3=60/100*x+3+80/100*x
9x/10-3=6x/10+3
x=60/3=20
9x/10-3=6x/10+3

Dear Student,
◆ Answer -
N = 135
● Explanation -
Let N be the number divided into x and y.
From given conditions,
80% of x = 60 % of y + 3
80/100 × x = 60/100 × y + 3
4x/5 = 3y/5 + 3
4x = 3y + 15 ...(1)
Also,
80% of y = 90% of x + 6
80/100 × y = 90/100 × x + 6
4y/5 = 9x/10 + 6
8y = 9x + 60 ...(2)
Solving (1) and (2),
x = 60
y = 75
Required number is
N = x + y
N = 60 + 75
N = 135
Hence, required no is 135.
Thanks dear. Hope this helps you...
