1.	Two numbers are in the ratio 7: 11. If 7 is added to each of the numbers, the ratio becomes 2: 3. Find the numbers.
Answer» Let the required numbers be 7x and 11x If 7 is added to each of them then (7x + 7)/ (11x + 7) = (2/3) 3 (7x + 7) = 2 (11x + 7) 21x + 21 = 22x + 14 22x – 21x = 21 – 14 x = 21 – 14 = 7 Thus the numbers are 7x = 7 (7) =49 And 11x = 11 (7) = 77

Answer»

Let the required numbers be 7x and 11x

If 7 is added to each of them then

(7x + 7)/ (11x + 7) = (2/3)

3 (7x + 7) = 2 (11x + 7)

21x + 21 = 22x + 14

22x – 21x = 21 – 14

x = 21 – 14 = 7

Thus the numbers are 7x = 7 (7) =49

And 11x = 11 (7) = 77
