Question

92: 11 :: 73:? (1) 15 (2) 16 (3) 18 (4) 17.​

Answer 1

We know that if,

$a:b :: c:d;\, then, \, ad = bc\, and \, \frac{a}{b} = \frac{c}{d}$

$\\Here, a = 92; b = 11; c = 73; d = x\\So, ad = bc\\\implies 92 \times x = 11 \times 73\\\implies x = \frac{803}{92} \\\\\implies x = 8\frac{67}{92} \, or\, 8.73 (approx.)$

Here is your answer.

Answer 2

$a:b :: c:d$

$ad= bc \: and \: \: \frac{a}{b} = \frac{c}{d}$

$92 \times x = 11 \times 73$

$92x = 803$

$x = \frac{803}{92}$

$x = 8.72$
