Question

Two numbers are in ratio 4:7. If their sum is 143,find the numbers​

Answer 1

Answer:

52,91

Step-by-step explanation:

Given that,

The Ratio of two numbers =4:7

Let, the numbers are 4x,7x

∵4x+7x=143

11x=143

x=13

⇒4×13= 52

⇒7×13= 91

CHECK

91 + 52= 143 [correct!]

[ the number which you asked in question!]

Answer 2

As per the data given in the question,

We have to divide 143 into two parts such that the parts are in ratio of 4:7.

So, let us assume that,

The parts are $4x\:and\:7x$ respectively.

So, total share will be $=(4x+7x) = 11x$

As 143 is divided into two parts.

So, we can say that, 11x should be equal to 143.

So, after solving the equation, we will get it as,

$11x = 143\\=>x = \frac{143}{11}\\=> x = 13$

Hence, value of both the numbers will be as,

$4x = (4\times 13) = 52\\7x = (7\times 13) = 91$
