243

Correct

3√? = 90.05 + 281 ÷ 4 – 151.06 90
= 90 + 280 ÷4 – 151 = 90 + 70 – 151 = 9
? = 9 x 9 x 9 = 729

Incorrect

3√? = 90.05 + 281 ÷ 4 – 151.06 90
= 90 + 280 ÷4 – 151 = 90 + 70 – 151 = 9
? = 9 x 9 x 9 = 729

175

140

Correct

? = 80.04% of 150.16 + 60.02% of 50.07 = 80% of
150 + 60% of 50
= 80 x 1.5 + 60 x 0.5 = 120 + 30 = 150

Incorrect

? = 80.04% of 150.16 + 60.02% of 50.07 = 80% of
150 + 60% of 50
= 80 x 1.5 + 60 x 0.5 = 120 + 30 = 150

Correct

? = √628 x 17.996 ÷ 15.04
= 625 × 18 ÷ 15 = 25 × 18 ÷15 = 30

Incorrect

? = √628 x 17.996 ÷ 15.04
= 625 × 18 ÷ 15 = 25 × 18 ÷15 = 30

(1/8) x 121 + (1/5) x 76 – ? =25
or, ? = (1/8) x 120 + (1/5) x 75 – 25 = 15 + 15 – 25 =
5

Incorrect

(1/8) x 121 + (1/5) x 76 – ? =25
or, ? = (1/8) x 120 + (1/5) x 75 – 25 = 15 + 15 – 25 =

319.85) = ?

238000

201300

234500

231000

213000

Correct

? = 849 × 11/16.13 × 441.26/20.98 ÷ 17.13/319.85
= 850 × 11/16 × 441/21 × 320/17 = 50 × 11 × 21 × 20
= 231000

Incorrect

? = 849 × 11/16.13 × 441.26/20.98 ÷ 17.13/319.85
= 850 × 11/16 × 441/21 × 320/17 = 50 × 11 × 21 × 20
= 231000

Question 8 of 20

8. Question

√[√(14640) + √? ] = 13

2400

2916

2305

2210

2350

Correct

13 = √[√(14640) + √? ]
Squaring both sides
or, 169 = {√[√(14640) + √? ]} 2 = √(14640) + √?
or, 169 = √(14640) + √? = 121 + √?
or, √? = 169 – 121 = 48
? = (48)2 = 2304 = 2305

Incorrect

13 = √[√(14640) + √? ]
Squaring both sides
or, 169 = {√[√(14640) + √? ]} 2 = √(14640) + √?
or, 169 = √(14640) + √? = 121 + √?
or, √? = 169 – 121 = 48
? = (48)2 = 2304 = 2305

2485

Correct

? = 5059 – 4567.8 + (221 x 9.7)
= 5060 – 4570 + (221 x 10) = 5060 — 4570 + 2210 =
7270 – 4570 = 2700

Incorrect

? = 5059 – 4567.8 + (221 x 9.7)
= 5060 – 4570 + (221 x 10) = 5060 — 4570 + 2210 =

1210

1075

1009

Correct

? = √1763.739 x √2400 ÷ 342.8998 +1082.98
= √1764 × (√2401 / 343) + 1083
= 42 × (49/343) + 1083 = 6 + 1083 = 1089 = 1090

Incorrect

? = √1763.739 x √2400 ÷ 342.8998 +1082.98
= √1764 × (√2401 / 343) + 1083

3√? x 32 + 13(104 – 91) = 585
or, 3√? x 32 + 169 = 585
3√? = (585-169) / 32 = 13
? = (13)3 = 2197 = 2200

Incorrect

3√? X 31.96 + 103.98 × 12.9765 – 90.954 x 13.003 =
585.0138
or, 3√? x 32 + 104 x 13 – 91 x 13 = 585
3√? x 32 + 13(104 – 91) = 585
or, 3√? x 32 + 169 = 585
