Simplification Test 5

Question : 25 of 40

Marks: +1, -0

Supply the two missing figures in order indicated by x and y in the given equation, the fraction being in their lowest terms:

5 1/x ×y3/4=20

Solution:

5 1/x ×y3/4=20

⇒{5x+1}/x×{4y+3}/4=20

⇒ (5x + 1) (4y + 3) = 80x

By putting x = y = 3, we get the required result.
Hence, x = 3, y = 3
