Question

7:15::x:30 please tell me
​

Answer 1

product of means = product of extremes

7 × 30 = 15 × x

210 /15 = x

70/5 = x

x = 14

Answer 2

Given :

• 7 : 15 :: x : 30

To Find :

• Value of x

Solution :

• As we know that the product of extremes is equal to product of means . Extremes are 7 and 30 whereas means are 15 and x . Now ,

$\implies \sf 7 \times 30\:=\: 15 \times x$

$\implies \sf 210\:=\: 15x$

$\implies \sf x\:=\: \dfrac{210}{15}$

$\implies \sf x\:=\:14$

• Value of x is 14
