Question

From the salary of a worker, $10\%$ is deducted as house rent, $15\%$ of the rest he spends on children's education and $10\%$ of the balance he spends on clothes. Now, he is left with Rs. $1377$. His salary is __________.

• A. Rs. $2000$
• B. Rs. $2040$
• C. Rs. $2100$
• D. Rs. $2200$

Answer 1

Answer: (A)

Rs. $2000$

let the salary be $x$ . Amount deducted in house rent is $\left(10x\right)/100=x/10$ so remaining salary is $9x/10$ and amount deducted on children's education is $\left(9x/10\right)\ast \left(15/100\right)=27x/200$ again calculate remaining amount it will be $153x/200$

now calculate deduction for the clothes also.. it will be $\left(153x/200\right)\ast 10/100=153x/2000$ again calculate remaining amount so it will be $1377x/2000$ which is equal to $1377$ so the salary will be $2000$.

Hence option A is correct.
