Question

7:x::35:45 then find the value
of x
​

Answer 1

Given :-

A proportion of 7:x::35:45

To Find :-

Value of x

SoluTion :-

Apply formula

Product of means = Product of exterms

$\tt \: 7 \times 45 = 35 \times x$

$\tt \: 315 = 35x$

$\tt \: x = \cancel \dfrac{315}{35}$

$\frak \red{x = 9}$

Hence :-

Value of x is 9

Answer 2

Answer :

• Value of x = 9.

Explanation :

Here, we are given with an expression in proportion.

We have to find the value of x.

Let's Begin.

7 : x :: 35 : 45.

We know that,

Product of Means = Product of Extremes.

Here,

• Means = 35 and x.
• Extremes = 45 and 7.

So,

➠ 35x = 45 × 7.

➠ x = (45 × 7)/35.

➠ x = 45/5.

➠ x = 9.

Therefore, Value of x = 9.

Verification :

Product of Means = Product of Extremes.

➠ 35 × 9 = 45 × 7.

➠ 315 = 315.

LHS = RHS.

Hence, Verified.
