A. Rs. 11,494.25

B. Rs. 20,000

C. Rs. 10,000

D. Rs. 15,000

Answer: Option C

Solution(By Examveda Team)

Let Ram's salary be x
He spends on rent = 30% of x = $$\frac{{30{\text{x}}}}{{100}}$$
He spends on education = 30% from rest of the salary = $$\frac{{30 \times 70{\text{x}}}}{{100 \times 100}} = \frac{{21{\text{x}}}}{{100}}$$
He Spends on clothes = 24% of total salary = $$\frac{{24{\text{x}}}}{{100}}$$
Saving = 2500
Salary of ram = x
$$\eqalign{ & \frac{{30{\text{x}}}}{{100}} + \frac{{21{\text{x}}}}{{100}} + \frac{{24{\text{x}}}}{{100}} + 2500 = {\text{x}} \cr & {\text{or,}}\,\frac{{75x}}{{100}} = {\text{x}} - 2500 \cr & {\text{or,}}\,75{\text{x}} = 100{\text{x}} - 250000 \cr & {\text{or, }}100{\text{x}} - 75{\text{x}} = 250000 \cr & {\text{or, x}} = \frac{{250000}}{{25}} \cr & {\text{or, x}} = 10000 \cr & {\text{Ram's}}\,{\text{salary = Rs}}{\text{.}}\,10000 \cr} $$

    Let the salary= 100
    Spend on rent=30% of 100=30
    Spend on education = 30% of the rest= 30% of (100-30)=21
    Spend on cloth= 24% of total salary= 24% of 100=24
    Saving= 100-(30+21+24)=25
    So now, 25=2500
    1=2500/25
    100=2500*100/25
    100=10,000
    Assumed money= real money
    So, Ram's salary=10,000
