* Supply the two missing figures in order indicated by x and y in the given equation, the fractions being in their lowest terms. 5 (1/x) x y (3/4) = 20

* Supply the two missing figures in order indicated by x and y in the given equation, the fractions being in their lowest terms.

5 (1/x) x y (3/4) = 20

A 3, 1

B 3, 3

C 4, 1

D 5, 3

Correct Answer: Option B

প্রদত্ত সমীক্রণ, {(5x + 1)/ x} x {(4y + 3)/ 4} = 20

⇒ (5x + 1) x (4y + 3) = 80x........(i)

Option check করলে দেখা যায়, x = 3 এবং y = 3 (i)নং সমীকরণকে সিদ্ধ করে।
