     Option D
    Solution:
    1 1/4 + 2 4/5 + 3 5/8 + 2 3/10
    [1 1/4 + 3 5/8] + [2 4/5 + 2 3/10]
    [1 + 3 + 1/4 + 5/8] + [2 + 2 + 4/5 + 3/10]
    [4 + 11/10] + [4 + 7/8]
    [4+ 4 + 11/10 + 7/8]
    [8 + 79/40] = 9 39/40
  3. 1008 ÷ 16 × 3/7 + 19 × 204 = 13 × 15 + x
    A) 5327
    B) 3099
    C) 3476
    D) 5376
    E) 3708
    View Answer
     Option E
     Solution:
    1008 ÷ 16 × 3/7 + 19 × 204 – 13 × 15
    1008/16 × 3/7 + 3876 – 185
    27 + 3876 – 185
  4. (0.6)5/4 ÷ (0.36)3/8 × (0.3)13/12 ÷ (0.09)7/24 = (0.18)1-x
    A) – 1/2
    B) 1/2
    C) – 4/3
    D) 1/4
    E) 5/6
    View Answer
     Option B
     Solution:
    (0.6)5/4 ÷ (0.36)3/8 = (0.6)5/4 ÷ (0.6)2 * 3/8 = (0.6)5/4 ÷ (0.6)3/4 = (0.6)5/4 – 3/4 = (0.6)1/2
    Similarly, (0.3)13/12 ÷ (0.09)7/24 = (0.3)1/2
    So (0.6)1/2 × (0.3)1/2 = (0.18)1/2
    So (0.18)1/2 = (0.18)1-x gives 1/2 = 1 – x, So x = 1/2
  5. 1 1/2 + 2 2/3 + 3 1/6 + 4 3/8 = x
    A) 11 8/15
    B) 10 5/21

     Solution:
    (0.4)17/16 ÷ (0.16)3/32 × (0.3)5/4 ÷ (0.09)-3/16
    = (0.4)7/8 × (0.3)7/8
