Answer 2

1. Answer: (c) 40%

Explanation: 2/5 = 2/5 x 100% 

= 40%

2. Answer: (d) 30%

Explanation: Number of students who like to watch T.V.

= 30% of 100

= 30/100 x 100 

= 30

3. Answer: (c) 4:1

Explanation: Number of Girls = 50 – 40 = 10

Required ratio = 40 : 10 

= 4 : 1

4. Answer: (d) Rs 40

Explanation:Out of Rs 100, money spent = Rs 80

∴ Out of Rs 200, money spent 

= 80/100 x 200 

= Rs 160

or

Money spent = 80% of Rs 200

= 200 x 80/100 

= Rs 60

∴ Money left = Rs 200 – Rs 160 

= Rs 40

5. Answer: (b) Rs 375

Explanation: M.P = Rs. 500 Discount = 10%

∴ S.P. = Rs.500 - 10% of Rs.500 

= 90% of Rs.500 

= 90/100 × Rs.500 

= Rs.450

Profit = 20% C.P. \(=\frac{450\times 100}{120}\)

= Rs.375

6. Answer: (b) 2000

Explanation: Given that 60% of x is 1200

\(\frac{60}{100}\times x=1200\)

\(x=1200\times\frac{100}{60}\).

x = 2000

7. Answer: (a) 29,484

Explanation: Let the rate of popukation be p,q,r respectively.

Therefore, population after 3 years is

\(=p(1+\frac{p}{100})(1+\frac{q}{100})\)\((1+\frac{r}{100})\)

 \(=2500\times(1+\frac{4}{100})(1+\frac{5}{100})\)\((1+\frac{8}{100})\)

\(=25000\times\frac{26}{25}\times\frac{21}{20}\times\frac{27}{25}\)

= 29,484

8. Answer: (a) 20 : 1

\(\frac{3}{5}=\frac{15}{x}\)

x = 25

12. Answer: (b) ₹ 25

Explanation: 8 : 20 = 10 : x

\(\frac{8}{20}=\frac{10}{x}\)

x = 25

13. Answer: (b) 25%

Explanation: \(\frac{1}{4}=\frac{1}{4}\times100\%\)

= 25%

14. Answer: (b) 10%

Explanation: \(0.1=\frac{1}{10}\)

\(=\frac{1}{10}\times100\%\)

= 10%

15. Answer: (d) 25%

So, for price including VAT Rs.110, the original price is Rs.100

Then, Price including VAT Rs. 3300, the original price

= Rs. \((\frac{100}{110}\times 3300)\)

= Rs. 3000

19. Answer: (c) 10

Explanation: Given, Amount = Rs. 220, Principle = Rs. 200, Time =1 year

1 year simple interest and compound interest are equal.

So Interest

=220−200

= Rs. 20

S. I = \(\frac{PRT}{100}\)

\(R=\frac{S.I\times100}{P\times T}\)

\(R=\frac{20\times100}{200\times1}\)

R = 10%

Answer 3

 20. Answer: (b) 2000

Explanation: Given that 60% of x is 1200

\(\frac{60}{100}\times x=1200\)

24. Answer:  (d) 50%

Explanation: The increase in the number of wins (or amount of change) =6 − 4 = 2

Percentage increase = \(=\frac{amount\;of\;change}{original\;amount\;or\;base}\times 100\)

\(=\frac{2}{4}\times100\)

= 50%

25. Answer:  (c) 10/9

Explanation: Amongst the given fractions \(\frac{5}{9},\frac{1}{9}\;and\;\frac{11}{9}\) the smallest is 1/9 and the largest is 11/9.

Now, consider the subtraction of the greatest and least fraction as follows:

\(\frac{11}{9}-\frac{1}{9}=\frac{10}{9}\)

Hence, the difference between the greatest and least numbers is 10/9.
