√1335 ≈ 36.5

36.5 × 24 = 876

√? + 876 − 13.96 = 895

√? = 895 − 862.04 = 32.96 ≈ 33

? = 33² = 1089

Hence, Option(c) is the correct answer.

y − x = 1
(y − x)² = 1

y + x = 8
xy = 3.5 × 4.5 = 15.75

Value = (1 ÷ 8) × 15.75 = 1.97 ≈ 2

The correct answer is Option D - None of these

Compute 15.332 - 12.942 = 2.390.

Add 22.062: 2.390 + 22.062 = 24.452.

Subtract 35.65: 24.452 - 35.65 = -11.198.

The final value is -11.198, which does not match any of the given numeric options; therefore the correct choice is None of these.

5.5% of 300 = 16.5
16.5 × 10 = 165

1404 ÷ x = 165 − 48 = 117

x = 1404 ÷ 117 = 12

14 × 9 = 126
189 ÷ 3 = 63

48% of x − 126 = 186

48% of x = 312

x = 312 ÷ 0.48 = 650

66% of 450 = 297
1014 ÷ 13 = 78
14 × 11 = 154

297 − 78 − x = 154

x = 65

45% of 280 = 126
4.5% of 40 = 1.8

LHS = 124.2

276 ÷ 23 = 12

√x = 124.2 ÷ 12 ≈ 10.35

x ≈ 108

a + b = 7
a − b = 2.6
a × b = 10.56

Value = (7 × 2.6) / 10.56 × 10

= 18.2 / 10.56 × 10
≈ 1.72 × 10
≈ 17.2

24.96 − 18.03 ≈ 6.93
41.92 − 32.05 ≈ 9.87

Total ≈ 6.93 + 9.87 = 16.8
