Question

112:5, 15:4"
?:7,
10:3​

Answer 1

Right answer for this series is  240.

Step-by-step explanation:

First take

          10:3​ ⇒ 10 × 3 = 30

          15:4 ⇒ 14 × 4 = 60

When we multiply 30 by 2 , we get 60

Now second part of the series

           112:5 ⇒ 112 × 5 =  560

           ?:7  ⇒ ? × 7 =  1680  (because when we multiply 560 by 3 we get 1680)

So,        $\frac{1680}{7}$      $= 240$

Thus, correct series is $112:5, 15:4, 240:7, 10:3$
