Answer:
Try to solve by this example it will help you
example: What number must be added to each of the
numbers 6, 15, 20 and 43 to make them
proportional ?
Answer : Let no. be ‘x’
∴ 6 + x/15 + x = 20 + x/43 + x
⇒ (6 + x)(43 + x) = (20 + x)(15 + x)
⇒ 258 + 49x + x2 = 300 + 35x + x2
⇒ 14x = 42
x = 3
∴ The required no is 3.
