1. A man invests Rs. 25,520 in mutual funds, which is 40% of his annual income. What is his monthly income?

1. Rs 5301.56
2. Rs 5303.12
3. Rs 5316.67
4. Rs 5322.78

Solution: Let the annual income of the man is Rs $$x$$ then. $$40 \ \% \ of \ x = 25520$$ $$\frac{40}{100} \times x = 25520$$ $$x = \left[\frac{25520 \times 100}{40}\right]$$ $$x = 63,800$$ The annual income of the man is Rs 63,800. Hence the monthly income of the man. $$= \frac{63,800}{12}$$ $$= Rs \ 5316.67$$

1. Which one value is greatest in 0.23, $$\frac{11}{23}$$, and $$12 \frac{1}{2} \ \%$$?

1. 0.23
2. $$\frac{11}{23}$$
3. $$12 \frac{1}{2} \ \%$$
4. None of them

Answer: (b) $$\frac{11}{23}$$

Solution: $$\frac{11}{23} = 0.47$$ $$12 \frac{1}{2} \ \% = \frac{25}{2} \ \%$$ $$= \frac{25}{2} \times \frac{1}{100}$$ $$= 0.125$$ Hence $$\frac{11}{23}$$ or 0.47 is the greatest value among them.

1. If the price of a laptop inclusive of sales tax of 6% is Rs 36,800 then find the market price of the laptop?

1. Rs 34716.98
2. Rs 34810.69
3. Rs 34866.38
4. Rs 34916.87

Solution: Let the market price of a laptop is Rs $$x$$ then. $$x + 6 \ \% \ of \ x = 36,800$$ $$x + \frac{6}{100} \times x = 36,800$$ $$100x + 6x = 36,800 \times 100$$ $$106x = 3,680,000$$ $$x = Rs \ 34716.98$$ Hence the market price of a laptop is Rs $$34716.98$$.

1. The difference between 46% of a number and 27% of the number is 6750. What is 15% of that number?

1. 5316.5
2. 5324.3
3. 5328.9
4. 5336.6

Solution: Let the number is $$x$$ then. $$46 \ \% \ of \ x - 27 \ \% \ of \ x = 6750$$ $$\frac{46x}{100} - \frac{27x}{100} = 6750$$ $$46x - 27x = 675,000$$ $$x = 35526.31$$ $$\approx 35,526$$ Now 15% of the number. $$= \frac{15}{100} \times 35,526$$ $$= 5328.9$$

1. If the difference between, the price of an item increased by 20% and the price of the item decreased by 25% is Rs 250 then find the original price of that item?

1. Rs 512.52
2. Rs 525.62
3. Rs 535.68
4. Rs 555.56

Solution: Let the original price of the item is Rs $$x$$ then. $$120 \ \% \ of \ x - 75 \ \% \ of \ x = 250$$ $$(120 - 75) \ \% \ of \ x = 250$$ $$45 \ \% \ of \ x = 250$$ $$\frac{45x}{100} = 250$$ $$x = \frac{250 \times 100}{45}$$ $$x = Rs 555.56$$ Hence the original price of the item is Rs 555.56.
