**Directions(1-5): **What will the approximate value of the following questions.

- 25.05 x 123.95 + 388.999 x 15.001 = ?
82507770893575848005Option C

25.05 x 123.95 + 388.999 x 15.001 = ?

= 25*123+388*15 = 8935 - 4376 + 3209 – 1784 +97 = 3125+?
25002000252020332773Option E

4376 + 3209 – 1784 +97 = 3125+?

=> 7682 – 1784 = 3125 + x

=> 5898 = 3125 + x

=> x = 5898 – 3125 = 2773 - 85% of 420 + ? % of 1080 = 735
4835554240Option B

85% of 420 + ? % of 1080 = 735

=> 357 + 10.8 x = 735

=> 10.8x = 735 − 357 = 378

=> x = 35 - 30% of 1225 – 64% of 555 = ?
1712141810Option B

30% of 1225 – 64% of 555 = ?

= 367.5 − 355.2 = 12.3 - 7/3 of 5/4 of 3024 = ?
85207000652088207220Option D

7/3 of 5/4 of 3024 = ?

= 35 × 252 = 8820 - If the rise in the population of City A from 2010 to 2012 was 2.75 lakh, what was its population in the year 2010?
6.05.54.22.53.3Option D

Let the population of City A in the year 2010 be x.

Then, its population in the year 2012 = x*140/100*150/100 = 2.1x

Difference = 2.1x – x = l.1x

=> 1.1x = 2.75 lakh

=> x =2.75/1.1 = 2.5 lakh - The population of City D in the year 2010 was approximately what per cent of its population in the year 2011?
47%44%50%57%67%Option D

Let the population of City D in the year 2010 be x.

Then population of City D in the year 2011 = x ×175/100

Required % = x *100/175x*100 = 57.14 == 57% - If the population of City E in the year 2010 was 3.2 lakh, what was its population in the year 2012?
6.00 lakh8.44 lakh5.02 lakh6.72 lakh7.77 lakhOption D

Population of E in the year 2012

= 3.2* 150/100* 140/100

= 6.72 lakh - In the year 2010, the population of cities B and F were equal, and the population of City F in the year 2012 was 5.4 lakh. What was the population of City B in the year 2012?
8.27.75.54.86.4Option C

Population of City F in the year 2010

= 5.4*100/180*100/125 = 2.4 lakh

[Population of B2010 = Population of F2010] Population of B2012 = 2.4* 160/100* 145/100

= 5.568 lakh - If the population of City C was 4.5 lakh in the year 2010, what was its population in the year 2012?
