3713 

Ans. 3725 

Solution: 

(35)2 + (30)2 + (40)2 = ? 

= 1225 + 900 + 1600 

= 3725 

 

Q.2 What value will come in place of question mark(?) in the following questions? 

2660 / 95 = ? + 22 

1.3 

2.11 

3.-4 

4.-3 

5.6 

Ans. 6 

Solution: 

? = 2660 \ 95 – 22 

= 28 – 22 

= 6 

 

Q.3 What value will come in place of question mark (?) in the following question? 

58/264 X 88/348 X ? = 11 

1.188 

2.202 

3.204 

4.198 

5.210 

Ans. 198 

Solution: 

? = (11 x 348 x 264)/(58 x 88) 

= 11 x ( 348/58) x (264/88) = 11 x 6 x 3 = 198 

 

Q.4 What value will come in place of question mark ? in the following question? 

√2916 + √4761 – √7921 = ? 

1.42 

2.41 

3.31 

4.34 

5.35 

Ans. 34 

Solution: 

54 = 2916, 69 = 4791, 89 = 7921 

? = √2916 + √4761 – √7921 

= 54 + 69 – 89 = 34 

 

Q.5 Find the wrong term in the series given below. 

10, 41,168,667,2672,10693 

1.168 

2.2672 

3.41 

4.10 

5.667 

Ans. 168  

Solution: 

The pattern is as follows 

10 x 4 + 1 = 41 

41 x 4 + 2 = 166 

166 x 4 + 3 = 667 

667 x 4 + 4 = 2672 

2672 x 4 + 5 = 10693 

 

Q.6 Find the wrong term in the series given below. 

1538, 1178, 866, 602, 386, 216 

1.1178 

2.386 

3.866 

4.602 

5.216 

Ans. 216 

Solution: 

First we find the difference, 

1538 – 1178 = 360 

1178 – 866 = 312 

866 – 602 = 264 

602 – 386 = 216 

Second difference, 

360 – 312 = 48 

312 – 264 = 48 

264 – 216 = 48 

216 – 170 = 46 

So, 218 should be in place of 216. 

Hence, option e. 

 

Q.7 Find the wrong term in the series given below. 

570, 282, 138, 54, 30, 12, 3 

1.12 

2.282 

3.54 

4.30 

5.138 

Ans. 54 

Solution: 

Logic for the given series: 

(570/2) – 3 = 282 

(282 / 2) – 3 = 138 

(138 / 2) – 3 = 66 

(66 / 2 ) – 3 = 30  

(30/2) – 3 = 12 

(12/2) – 3 = 3 

SO, wrong term = 54 

 

Q.8 Find the wrong term in the series given below. 

10, 36, 69, 117, 180, 260 

1.10 

2.36 

3.180 

4.117 

5.69 

Ans. 36 

Solution: 

The pattern in as follows: 

10 + (52 – 1) = 34 

34 + (62 – 1) = 69 

69 + (72 – 1) = 117 

117 + (82 – 1) = 180 

180 + (92 – 1) = 260 

 

Q.9 In the following questions two equations numbered I and Il are given. You have to solve both the equations and choose the correct option. 

1. x2 +26x +165 = 0 

2. Y2 +38y +345 = 0 
1. ×
2. x > y 

3. X ≤ Y 

4. x≥ y 

5. X = y or relationship cannot be established 

Ans. x≥ y 

Solution: 

From equation 1. 

x2 +26x +165 = (x+11)(x + 15) =0 

  • X = -11, -15 

From equation 2: 

Y2 + 38 y + 345 = (y+15)(y + 23)=0 

  • Y = -15, -23 

 

X = -11 

X = -15 

Y= -15 

X > y  

X = y  

Y= -23 

X >y 

X > y 

So , x ≥ y 

 

Q.10 In the following questions two equations numbered 1 and 2 are given. You have to solve both the equations and choose the correct option. 

1. x2 +30x +221 = 0 

II. y2 +24y +143 = 0 

1.x < Y 

2.x > y 

3.x ≤ y 

4.x ≥ y  

5.x = y or relationship cannot be established 

Ans. x ≤ y  

Solution: 

x2 +30x +221 = ( x -17) ( x + 13) = 0 

  • x = -17, -13 

From equation 2: 

. y2 +24y +143 = (y + 13)(y + 11) = 0 

  • y = -13, -11 

 

X = -17 

X = -13 

Y = -13 

X < y  

X = y 

Y = -11 

X < y 

X < y 

 

SO, x ≤ y
