Question

Date:
The sum of two number is 80 and there
ratio is 3:5 find the greatest number​

Answer 1

Answer:

We have to divide 80 in two parts with ratio 3 and 5.

Let us take first part A to be 3 equal parts and second part B to be 5 equal parts.

So how many parts in total we have?

We have 3 parts + 5 parts = 8 parts

That is we have to divide 80 in 8 equal parts

And we get,

80÷8=10

That means each part is equal to 10

Now we can calculate the share of A and B easily .

A has to get 3 parts,

So, A= 3×10=30

and B has to get 5 parts,

B=5×10=50

A:B=3:5

but numbers are 30 and 50 which we get after dividing 80 in 3:5

Answer 2

Step-by-step explanation:

Question :-

• The sum of two number is 80 and their ratio is 3:5. Find the greatest number.

To Find :-

• Greatest number.

Solution :-

Given :

• Sum of numbers = 80
• Ratio of numbers = 3:5

Let us consider the two numbers be 3x and 5x.

According to the question,

${\sf{\longrightarrow 3x\ +\ 5x\ =\ 80}}$

${\sf{\longrightarrow 8x\ =\ 80}}$

${\sf{\longrightarrow x\ =\ \dfrac{80}{8}}}$

${\sf{\longrightarrow x\ =\ 10}}$

Putting the value of x,

• First number = 3x = 3 × 10 = 30
• Second number = 5x = 5 × 10 = 50

$\therefore$ Hence, the greatest number is 50.
