How much will be decreased to each terms of ratio 16 : 19, so that it will be 7 : 6?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e 37
Let the number which is subtracted from both terms be 'x'
⇒ (16 - x) / (19 - x) = 7 / 6
⇒ 6(16 - x) = 7(19 - x)
⇒ 96 - 6x = 133 - 7x
⇒ x = 37
