What should come in place of question mark (?) in the following question?

(474552)1/3 – (6084)1/2 + 68 – 7.8 = ?
» Explain it
B
? = (474552)1/3 – (6084)1/2 + 68 – 7.8

? = (783)1/3 – (782)1/2 + 68 – 7.8

= 78 – 78 + 68 – 7.8 = 60.2

Hence, option B is correct.

What should come in place of question mark (?) in the following question?

 27 13 + 23 14 + 28 12 – 17 21 + 0.85 – 0.37 = ? 30 25 15 45
» Explain it
A
 ? = 27 13 + 23 14 + 28 12 – 17 21 + 0.85 – 0.37 30 25 15 45

 ? = (27 + 23 + 28 – 17) + ( 13 + 14 + 12 – 21 ) + 0.48 30 25 15 45

 ? = 61 + ( 195 + 252 + 360 – 210 ) + 48 450 100

 = 61 + 597 + 48 = 61 + 1194 + 432 450 100 900

 = 61 + 1626 = (61 + 1) + 726 900 900

 = 62 + 121 = 62 121 150 150

Hence, option A is correct.

3
What should come in place of question mark (?) in the following question?

 294 + 726 + 1176 + 486 – 600 = ?
» Explain it
C
 ? = 294 + 726 + 1176 + 486 – 600

 ? = 6 × 49 + 6 × 121 + 6 × 196 + 6 × 81 – 6 × 100

 ? = 7 6 + 11 6 +14 6 + 9 6 – 10 6

 = 6 (7 + 11 + 14 + 9 – 10) = 31 6

Hence, option C is correct.

4
What should come in place of question mark (?) in the following question?

(531441)1/3 ÷ 9 ×
 4096
+
 6561
– 16 = ?
8 9
» Explain it
B
? = (531441)1/3 ÷ 9 ×
 4096
+
 6561
– 16
8 9

 = 81 ÷ 9 × 64 + 81 – 16 8 9

= 9 × 8 + 9 – 16 = 65

Hence, option B is correct.

5
What should come in place of question mark (?) in the following question?

164.2 × 2562.1 × 142 × 1963.2 = ?
» Explain it
A
? = 164.2 × 2562.1 × 142 × 1963.2

= 164.2 × 16(2×2.1) × 142 × 14(2×3.2)

= 164.2+4.2 × 142+6.4

= 168.4 × 148.4 = (16 × 14)8.4 = 2248.4

Hence, option A is correct.
