**Solutions for IBPS Clerk numerical ability questions:Â (1Â toÂ 8)**

**1)**Â AnswerÂ (E)

TimeÂ takenÂ byÂ ShwetaÂ toÂ completeÂ 300Â unitsÂ ofÂ workÂ atÂ aÂ speedÂ ofÂ 15units/minÂ =Â 300/15Â =Â 20

NewÂ speedÂ =Â 1.4*15Â =Â 21Â units/min

TimeÂ takenÂ byÂ ShwetaÂ toÂ completeÂ 300Â unitsÂ ofÂ workÂ atÂ aÂ speedÂ ofÂ 21units/minÂ =Â 300/21Â ~14

TimeÂ differenceÂ =Â 6Â minutes

**2)**Â AnswerÂ (E)

9070Â –Â 15^3Â =Â 5675Â ,Â 5675Â –Â 13^3Â =Â 3478Â ,Â 3478Â –Â 11^3Â =Â 2147Â ,Â 2147Â –Â 9^3Â =Â 1418Â ,Â 1418Â –Â 7^3Â =Â 1075Â â‰ Â 1077Â ,Â 1075Â –Â 5^3Â =Â 950

**3)**Â AnswerÂ (C)

WithÂ theÂ currentÂ =>Â downstream

AgainstÂ theÂ currentÂ =>Â upstream

LetÂ theÂ speedÂ ofÂ theÂ boatÂ beÂ â€˜sâ€™Â andÂ theÂ speedÂ ofÂ theÂ riverÂ beÂ â€˜râ€™.

So,Â sÂ â€“Â rÂ =Â 5Â andÂ sÂ +Â rÂ =Â 15

=>2sÂ =Â 20Â =>Â sÂ =Â 10Â andÂ rÂ =Â 5Â kmph

SpeedÂ ofÂ theÂ currentÂ =Â 5Â kmph

**4)**Â Answer (B)

Let the marked price be Rs. 100.

Then cost price = 100 â€“ 40 = Rs. 60

Selling price = 100+ 50 = Rs. 150

Profit = 150 â€“ 60 = 90

Profit%=90/60Ã—100=150%

**5)**Â Answer (A)

Let the two numbers be p,q

75% of p means 75/100*p or

3/4 of p, 4/5 of other number means 4/5q.Both are equal.

Hence,3/4p=4/5q hence,p/q=16/15.

Hence the ratio is 16:15,hence, A

**6)**Â Answer (D)

Let the earnings of A and B be 8k and 9k respectively.

New earnings of A = 150/100 * 8k = 12k

New earnings of B = 3/4 * 9k = 6.75k

So, 12k : 6.75k = 16 : 9

But, from this equation, we cannot determine the value of k.

So, option d) is the correct answer.

**7)**Â AnswerÂ (D)

(7-1)Â xÂ 2Â =Â 12

(12Â â€“Â 2)Â xÂ 4Â =Â 40

(40Â â€“Â 3)Â xÂ 6Â =Â 222

(222Â â€“Â 4)Â xÂ 8Â =Â 1744Â â‰ Â 1742

(1744Â â€“Â 5)Â xÂ 10Â =Â 17390

(17390Â â€“Â 6)Â xÂ 12Â =Â 208608

**8)**Â AnswerÂ (A)

LetÂ P+Q+R+SÂ =Â xÂ whereÂ xÂ isÂ bagÂ ofÂ fruits.

PÂ =Â (3/8)x

QÂ =Â (1/5)*5x/8Â =Â x/8

LetÂ RÂ andÂ SÂ beÂ fractionÂ byÂ y.

FruitsÂ withÂ RÂ andÂ SÂ =Â xÂ -3x/8Â –Â x/8Â =Â x/2

SOÂ fruitsÂ withÂ RÂ =Â x/4
