Detailed Solutions for the above Aptitude Questions:

1).  ? = 19.9 × 16.1 × 17.2 = 5510.708

Answer: c)

2).  ? = 14 1/11 + 16(3/11) + 14 (4/121) + 15 (3/11)

= (14+16+14+15) (1/11 + 3/11 + 4/121 +3/11)

= 59[ (11+33+4+33)/121 ] = 59(81/121)

= 59(81/121)

Answer: e)

3). ? =16.5% of 300 + 70.5% of 1400 – 10% of 480

= [(16.5/100) × 300] + [(70.5/100) × 1400] – [(10/100) × 480]

=149.5 + 987 + 48 = 1084.5

Answer: b)

4).  ? = (4 × 4 × 4 × 4)² – (2³)² ÷ 16

= 65536 – 64 ÷ 16 = 65536 – 4 = 65532

Answer: d)

5). 19% of 360 + ? = 45% of 230

Or, 19/100 × 360 + ? = 45/100 × 230

Or, 68.4 + ? = 103.5

Or, ? = 35.1

Answer: e)

6).  ? = 49 ÷ 0.7 – 4.9 = 49 ÷ (7/10) – 4.9

= 49 × 10/7 – 4.9 = 70 – 4.9 = 65.1

Answer: b)

7). ? = (√576 + √1225+√289) × √5625)

= (24 + 35 + 17) × 75 = 76 × 75 = 5700

Answer: d)

8). ? = 9898 + 1773 – 1882 × 3 ÷ 2

= 9898 + 1773 – 941 × 3

= 11671 – 2823 = 8848

Answer: c)

9). ? = ₃√729 × ₃√15625 × √3969 ÷ 21

= 9 × 25 ×63 ÷ 21 = 675

Answer: e)

10). ? = √7744 × √? = 15488

Or, 88 × √? = 15488

Or, √? = 15488/88 = 176

Or, ? = 30976

Answer: b)
