Friends, here are the solutions for our IBPS and SBI Associates Clerks Numerical Ability Practice Test. Please take the test from here  and try to solve them on your own before checking these solutions. All the Best :)

1.

37% of 1264 + ? = 999

467.68 + ? = 999

? = 999 - 467.68 = = 531.32

2.

(23)² + (41)² = (?)² + 94

(?)² = 529 + 1681 - 94

=> (?)² = 2116 = (46)² 

=> ? = 46

3.

√(√(3844) - √((152)+(17))) = √?

=>  √? = √(√(3844) - √(169))

=>  √? = √(62-13) = √49

 => ? = 49

4.

(1438% of 36) % 24 = ?

=> 517.68 % 24 = 21.57

5.

5(1/7) x 8(1/6) % 7(7/8) = ?

=> (36/7) x (49/6) x (8/63) = 16/3 = 5(1/3)

6.

Let the monthly income be Rs. 100

Money spent on rent = Rs. 22

House hold expenditure = Rs. 17

Children's education = Rs. 11

Remaining money = 100 - (22 + 17 + 11)

                                       = 50

Money on travelling = 30% of 50 = Rs. 15

Remaining = 50 - 15 = Rs. 35

According to question, he saves Rs. 2,100

=> 35% = Rs. 2,100

100% (Total Money) = (100/35) x 2100 = Rs. 6,000

Monthly Salary = Rs. 6000

=> Yearly salary = 12 x 6000 = Rs. 72,000

7.

Total marks in Hindi & English = 85 x 2 = 170

Total marks in Maths & Science = 90 x 2 = 180

Marks in social = 86

Total marks in all 5 subjects = 170 + 180 + 86 = 436

=> Percentage of Marks in all subjects = (436/500) x 100 = 87.2

8.

Distance = Speed x  Time

Let the length of the birdge be "X" metres

=> 240 + X = 45 x (5/18)mps x 36 sec

=> X = 210 metres

9.

3/5 = 0.6, 8/11 = 0.72, 5/8 = 0.625, 4/7 = 0.57 and 6/13 = 0.46

after arranging in ascending order, last in the order is the biggest fraction

=> Biggest fraction is 8/11

10.

14 x 135 = 21

21 x 2 = 42

42 x 2.5 = 105

105 x 3 = 315

315 x 3.5 = 1102.5

11.

(4/5) x 1630 - (2/3) x 1140

=> 1304 - 760 = 544

12.

Population after 2 years = 105% of 108% of 334000

=> (105/100) x (108/100) x 334000 = 378756

13.

Number of days in Sep & Oct = 30 + 31 = 61

=> Required quantity of rice = (105/7) x 61 = 915 kgs

14.

Let the fraction be 100X / 100Y

=> (100X + 200X) / (100Y  + 150Y) = 3/4

=> 300X / 250Y = 3/4

=> X/Y = 5/8

15.

A's one day work = 1/40

A & B together one day's work = 1/24

B's one day work = (1/24) - (1/40) = 1/60

=> B can complete that work in 60 days

16.

Average = (382 + 493 + 194 + 248 + 385 + 704 + 482 + 104) / 8

= 2992 / 8 = 374

17.

Let the breadth of the rectangle be "X" cm

Perimeter of the rectangle = 2(l+b)

=> 2 (32 + X)= 112 = > X =24

=> Area of the rectangle = l x b = 32 x 24 = 768

18.

P = 14000,  SI = 2100,   T = 3

SI = PTR/100

=> R = (SI x 100) / (P x T)

= (2100x100) / (14000x3)  = 5%

now P=14000,  T=3,  R=5

Amount = 105% of 105% of 105% of 14000

 =   16206.75

=> C.I = 16206.75 - 14000 = 2206.75

19.

Let's Ravi's salary be "X" and Raju's be "Y"

=> 4/5 x X = 2/3 x Y

=> X/Y = 5/6  => X:Y = 5:6

=> Ravi's salary = (5/11) x 55000 = Rs. 25,000

20.

2100x12 : 3500x9 = 4:5

Bheem's share = (5/9) x 5400 = Rs. 3000
