Answer With Explantion:

  1. Answer c

Explanation:

(5/11) × (4/5) × (11/16) × 848 = x

X = 212

2. Answer b

Explanation:

(1782/12) × (1/3) × 36 + (25/100) × 540 – (67/100) × 1300 = x

1782 + 135 – 871 = x

X = 1046

  1. Answer d

Explanation:

(57/7) × (28/5) × (5/12) = x

X= 19

  1. Answer e

Explanation:

(42/100) × 250 – (55/100) × 880 +11x =61

11x = 61 – 105 + 484

11x = 440

X = 40

  1. Answer a

Explanation:

(3/7) × 266 ÷ 18 + 14 = √x

(3 × 38)/18 +14 = √x

(19/3) +14 = √x

√x = 61/3

X= 3721/9

  1. Answer b

Explanation:

Let total sum be x,

A= (2/5)x +35

B = (1/5)x – 75

C= 350

A+B+C =x

(2/5)x +35 + (1/5)x – 75 +350 =x

(3/5)x +310 = x

310 = x- (3/5)x

(2/5)x = 310

X= 310*(5/2) = 775

  1. Answer c

Explanation:

Let us assume, CP = 100

MP= 100*(125/100) = 125

SP = 125*(70/100) = 87.5

Loss % = (12.5/100)*100 = 12.5 %

  1. Answer a

Explanation:

The angles of quadrilateral are in the ratio of 3:2:5:8.

Total angles = 360

18’s = 360

1’s = 20

The angles are,

= > 60◦, 40◦, 100◦, 160◦

Second smallest angle of quadrilateral = 60◦ = Second smallest angle of triangle

One of the angles of triangle = 2* 40◦ = 80◦

Total angles of triangle= 180◦

Remaining angle = 180 – (60+80) = 40◦

Largest angle of triangle = 80◦

  1. Answer d

Explanation:

T= D/ S

Two trains running in opposite direction, so,

Relative Speed = S1 +S2 = 65 + x (Let speed of second train be x)

15 = (275+300)/ ((65+x)*(5/18))

15*(65+x)*5 = 575*18

65+x = 138

X= 138 -65 = 73 km/hr

  1. Answer b

Explanation:

Increased weight = 8*2 = 16 kg

So 2 women’s weight = 62kg +16 kg = 78 kg

Average weight of 2 women = 78/2 = 39 kg

  1. Answer a

Explanation:

The pattern is, *0.5+1, *1 +1, *1.5 +1, *2+1, *2.5 +1,..

The answer is, 346

  1. Answer c

Explanation:

The difference of difference is, 5, 7, 9, 11

The answer is, 133

  1. Answer d

Explanation:

The pattern is, *(12 +1), *(22 +1), *(32 +1), *(42 +1), *(52 +1),..

The answer is, 3400

  1. Answer c

Explanation:

The pattern is, – (53 – 1), – (43 – 1), – (33 – 1), – (23 – 1),..

The answer is, 1005

  1. Answer a

Explanation:

The difference is, (83+1), (73-1), (63+1), (53-1), (43+1)

The answer is, 1198

  1. Answer a

Explanation:

Total soldiers joining BSF in the years 2010, 2012 and 2014 = (4.8+5.2+7.2) = 17.2 thousands

Total number of soldiers joining Navy over all the years = (0.75+1.2+1.8+3.25+4.25+5.2) = 16.45 thousands

Required percentage = (17.2*100)/16.45 = 104.5 = 105%

  1. Answer b

Explanation:

Total number of soldiers joining Army in the year 2010 and 2012 = (4.5+8.5) = 13 thousands

Total number of soldiers joining Army in the year 2013 and 2014 = (6.2+7.8) = 14 thousands

Required ratio = 13/14 = 13 : 14

  1. Answer a

Explanation:

Total number of soldiers joining Air force in the year 2010, 2012 and 2014 = (2.8+4.5+5.2) = 12.5 thousands

Total number of soldiers joining Army in the year 2014 = 7.8 thousands

Required difference = (12.5 – 7.8) thousands = 4.7 thousands = 4700

  1. Answer a

Explanation:

According to graph only Navy soldiers joining continuously increased from the year 2012 to 2015

  1. Answer c

Explanation:

Total number of soldiers joining in Army, Navy and Coast guard forces in the year 2013

= (6.2+3.25+5.2) thousands = 14.65 thousands = 14650
