Directions (Q. 1 – 5):

1.Answer c

 (3840/15) + (2224/8) – 142 = x

X = 256 + 278 – 196

X = 338

2.Answer a

4x × 15 = (48096/8) + 9348

4x × 15 = 6012 + 9348

4x = 15360/15

4x = 1024

4x = 45

X = 5

 3.Answer d

 [((11500/4)/25) + (64 × 16)1/2] = x

115 + (641/2 × 161/2) = x

115 + (8*4) = x

115 + 32 = x

X = 147

4.Answer b

3 5/8 + 9 ¾ – 5 ½ – 3 1/8 + 7 ½ =?

(3 + 9 – 5 – 3 + 7) (5/8 + ¾ – ½ – 1/8 + ½) = x

11 [(5 + 6 – 1)/8] = x

X = 11 (10/8) = 11 (5/4) = 12 (¼)

5.Answer c

∛35937 ÷ 11 × 22 + 123 + 527 = x

(33/11)*22 + 1728 + 527 = x
