a)┬а4475
b)┬а4575
c)┬а4775
d)┬а4875

1/4th of 1/2 of 3/4th of 52000

тЗТ (1/4)┬а├Ч (1/2)┬а├Ч (3/4)┬а├Ч 52000┬а

тЗТ (52000 ├Ч 3)/32

тЗТ 1625┬а├Ч 3┬а

тЗТ 4875

4.┬аWhat will come in place of question mark in the following equation?

283 ├Ч 56 + 252 = 20 ├Ч ?

a) 905
b) 605
c)┬а805
d) 705

283 ├Ч 56 + 252 = 20 ├Ч x

тЗТ 15848 + 252 = 20┬а├Ч x

тЗТ 16,100 = 20┬а├Ч x

тЗТ x = 805

5. What will come in place of question mark (?) in the following question?

(5863 - тИЪ2704) ├Ч 0.5 = ?

a)┬а2705.5
b)┬а2605.5
c)┬а2905.5
d)┬а2805.5

(5863 - тИЪ2704) ├Ч 0.5 = x

тЗТ (5863 тАУ 52) ├Ч 0.5 = x

тЗТ x = 2905.5

6.┬аWhat will come in place of question mark (?) in the following question?

76% of 1285 = 35% of 1256 + ?

a)┬а527
b)┬а537
c)┬а547
d)┬а557

76% of 1285 = 35% of 1256 +?

тЗТ (76/100) ├Ч 1285 = (35/100) ├Ч 1256 +?

тЗТ 97660/100 = 43960/100 +?

тЗТ ? = (97660/100) тАУ (43960/100)

тЗТ ? = 53700/100 = 537

7.┬а In the following question, two equations numbered I and II are given. You have to solve both the equations and give answer

тИЪ360 y + тИЪ200 = 0

a) x < y
b) x > y
c) x = y
d) none of the above

x = -тИЪ402/тИЪ500 =┬а-тИЪ(402 ├Ч 18)/тИЪ(500┬а├Ч 18) =┬а-тИЪ7236/тИЪ9000

y = -тИЪ200/тИЪ360 =┬а-тИЪ(200 ├Ч 25)/тИЪ(360┬а├Ч 25) =┬а-тИЪ5000/тИЪ9000

Now, as┬а-тИЪ7236 <┬а-тИЪ5000

Hence, x < y.

8.┬аThe sum of 15% of a positive number and 20% of the same number is 126.What is one-third of that number?

a)┬а100
b)┬а120
c)┬а140
d)┬а160

Let the number = x

According to the question

тЗТ (15/100) ├Ч x + (20/100) ├Ч x = 126

тЗТ (35/100) ├Ч x = 126

тЗТ x = 12600/35 = 360

We want to find out x/3

тИ┤ x/3 = 360/3 = 120

9.┬аIf 70% of a number is subtracted from itself it reduces to 81.what is two fifth of that no.?

a)┬а108
b)┬а118
c) 98
d)┬а128

Let the number be m.

Then m тАУ 70 % of m = 81

тЗТ m тАУ 70/100 ├Ч m = 81

тЗТ m тАУ 0.7m = 81

тЗТ 0.3m = 81

тЗТ m = 81/0.3

тЗТ m = 270

According to question:

Now, we need to find 2m/5

= 2 ├Ч 270 / 5

= 2 ├Ч 54

= 108

10.┬аWhat will come in the place of the question mark '?' in the following question?

986 ├Ч 237 + 986 ├Ч 863 = ?

a)┬а1064600
b)┬а1074600
c)┬а1094600
d)┬а1084600

We are given 986 x 237 + 986 x 863

Hence taking 986 common

We have 986 ├Ч (237 + 863)

? = 986 ├Ч 1100

? = 1084600
