Question

What is the sum whose 25% is Rs.1250 ?

Answer 1

5000 is the sum whose 25% is 1250

as we know 25% is 1/4 th of 100% so multiply 1250*4 and we get 5000 and to cross verify 5000/1250 is 0.25 which multiplied by 100 is 25%

or directly solving we can write

25% as (25/100)* x  = 1250

x = 1250 * 100/25 or directly 4

then x= 1250 * 4

then the number is 5000

Answer 2

Answer :-

• The sum is Rs 5000.

To find :-

• The sum whose 25% is Rs 1250.

Solution :-

Let the sum be "x".

It is given that :-

• 25% of x is Rs 1250.

Therefore,

$\sf25\% \: of \: x = 1250$

Converting 25% into fraction,

$\sf \dfrac{25}{100} \times x = 1250$

Multiplying 25/100 with x,

$\sf\dfrac{25x}{100} = 1250$

Transposing 100 from LHS to RHS, changing it's sign,

$\sf25x = 1250 \times 100$

Multiplying 1250 with 100,

$\sf25x = 125000$

Transposing 25 from LHS to RHS, changing it's sign,

$\sf x = \dfrac{125000}{25}$

Dividing 1250000 by 25,

$\underline{ \boxed{\sf x = Rs \: 5000}}$

Hence :-

• The sum whose 25% is Rs 1250 is Rs 5000.
