Here we are providing you some questions for practice:

Simplifications: 

Word problems questions : 

The compound interest earned on a sum in 3 years at 15% per annum compounded annually is Rs.25002. Find the sum?

	1. 45000 Rs	2. 48000 Rs
	3. 40000 Rs	4. 36000 Rs
	5. None

As we know

required answer  = 

1. A broker gets a commission of 8% on the sale up to Rs. 8000 and a commission of  10% on the sale above Rs. 8000. If he returns a sum of Rs. 12310 to the company after deducting his commission, what was  total sale of company ?

1. 13500 Rs	2. 13800 Rs
3. 12900 Rs	4. 12500 Rs
5. None of these

Let total sale be x

92% of 8000 + 90% (x - 8000) = 12310

After solving x = 13500

5. A vessel contains a mixture of milk and water in ratio 4:3. If 14 litres of mixture is taken out and replaced with water, the ratio of milk and water  becomes 3:4. Find the initial quantity of mixture?

1. 45 litres	2. 64 litres
3. 84 litres	4. 56 litres
5. None of these

(4 : 3)3 = 12 : 9

(3: 4)4 = 12 : 16

Difference 7=14 

So 28=56 litres

Number series questions

In the following number series find the missing term- 18       12        8          7         ?
1. 6.2	2. 7.4
3. 5.5	4. 6
5. 8

the given pattern is 

2+3      3+4    4+5     5+6

hence the next term should be 7.4

In the following number series find the missing term- 111    123     153     209     299    ?
1. 420	2. 425
3. 388	4. 431
5. None of these

The given pattern is

Add 34    56    78    910      1112   

Hence the next term should be 431

Approximations questions

In the following questions find the approximate value of question mark (?)

144% of 1280 - ?% of 1850 = 112.5% of 900

	1. 31.5	2. 22.5
	3. 44.9	4. 62.5
	5. 55.4

Answer:

1843.2 – ?% of 1850 = 1012.5

In the following questions find the approximate value of question mark (?)
1. 2.45	2. 1.80
3. 3.43	4. 4.22
5. 5.25

Data interpretations questions :

 Read the given information carefully to answer the questions asked-

Following bar graph shows the profit/loss percentage of five different companies over three different years-

 

	If in year 2010-11 income of company D was equal to the income of same company in year 2012-13. Then find the ratio of expenditure of company D in year 2010-11 to 2012-13.
	1. 14:25	2. 25:14
	3. 5:6	4. 6:5

70% of CP 10-11=125% of CP 12-13

If the income of company C in all given years were equal, then find the respective ratio of its expenditure in all given years.(2010-11:1211-12:2012-13)
1. 26 : 24 : 25	2. 25 : 24 : 26
3. 312 : 325 : 300	4. 300 : 325 : 312
5. None of these

On solving

CP1: CP2 : CP3=312 : 325 : 300

Inequality questions :

In the following question find the values of variables and state the correct relationship-
1. x < y 2.  x < y 3. x > y 4.   x > y 5.  x = y or relationship cannot be established

In the following question find the values of variables and state the correct relationship-

1.  x < y 2.   x < y 3.  x > y 4.    x > y 5.  x = y or relationship cannot be established
