Question

10- Determine, if the following are in proprotion
32,48,79,210
​

Answer 1

Answer :

• 32, 48, 79, 210 are not in proportion.

Given :

• Numbers 32,48, 79 and 210.

To Find :

• We need to determine whether the following numbers are in proportion or not.

Calculation :

Knowledge required :

• For finding out whether the numbers are in proportion or not, we need to apply this concept :-

$\underline{ \boxed{ \sf{Product \: of \: extremes = Product \: of \: means}}}$

Here,

$\Rightarrow$ Product of extremes = 32 × 210

$\Rightarrow$ Product of extremes = 6720

$\Rightarrow$ Product of means = 48 × 79

$\Rightarrow$ Product of means = 3792.

We observed that :-

• Product of extremes ≠ Product of means.

Therefore,

• 32, 48, 79 and 210 are not in proportion.
