Answer 1

HELLO DEAR,

WHERE,

P=14,
Q=16

R=x
S=24

p : q : : r : s

⇒ ps = qr

$14 \times 24 = 16 \times x$
$14 \times 24 = 16 \times x \\ = > x = \frac{14 \times 24}{4 \times 4 } \\ = > x = \frac{7 \times 6}{2} = 21 \\ = > x = 21$
I HOPE ITS HELP YOU DEAR,
THANKS

Answer 2

hello...

CORRECT OPTION IS B 21.

EXPLANATION :-

$GIVEN :- A = 14 , B = 16 , C = 24$
$To find :- value of D$
$p : q :: r : s$
$ps = pq$
$x = 14 \times 24 \div 4 \times 4$
$x = 7 \times 6 \div 2$
$x = 21$
$x = 21 ans$
