Question

Raj deposits 12.5% of his salary in provident fund and spends 70% of the remainder. Finally, he is left with Rs. 210. What is his salary?​

Answer 1

Step-by-step explanation:

12.5%=1/8 or 70%=7/10

So take lcm(8,10)=80

Let total salary=80

Provident fund=12.5%of80=1/8×80=10

Remaining=80-10=70

Spend=70%of70=7/10×70=49

Left amount=70-49=21

Here

21=210(given)

1=210/21=10

So

Salary=10×80=800

Answer 2

Answer:

He had a total sum of 2400 Rupees.

Step-by-step explanation:

Given Information,

He deposited the 12.5%

Let's assume the value to be "P",

Rest of which he spent,

So, 70% of 12.5% will be nothing but,

= P (0.7 x 0.125)

= P (0.0875)

It means that he has spent his 87.5% of the salary,

Now he has left with, 8.75%

or in value terms, Rs. 210

Now, this Rs. 210 is equal to the 8.75% of the salary,

If,

210 = 8.75%

then,

1% = 210/8.75

100% = (210 x 100)/8.75

100% = 2400

He had a total sum of 2400 Rupees.
