    B) 144
    C) 136
    D) 196
    E) 148
    View Answer
     Option A
  2. 1 1/4 + 2 4/5 + 3 5/8 + 2 3/10 = x
    A) 10 19/40
    B) 9 17/30
    C) 9 19/25
    D) 8 29/35
    E) 9 39/40
    View Answer
     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
    C) 11 17/24
    D) 12 3/10
    E) 10 13/21

    A) 7/8
    B) 1/5
    C) 7/5
    D) 9/13
    E) 6/11     
    View Answer
     Option A
     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
  7. 3 9/14 × 1 4/17 × 2 16/18 – 2 3/4 = x
    A) 11 1/3

    ty mam 🙂

  2. aspirant

    mam,answer of q5 should be 11 17/24,nd in q6 replace(-3/16) by (3/16)

    1. 5th is correct, check again

      yes in 6th, no – sign

  3. Pawan Kandpal

    please check question(6) there should not be – sign in front of 3/9

      any short approach for ques. 7 ??

      1. !!angry bird !!

        no sir 🙁

      2. Ankush Choudhary

        yes…..do it by solving the fraction and relate with the nearby fractions in the option

        1. ครђ

          Could you please elaborate? 🙂

          1. Ankush Choudhary

            yes why not…
            see its hard to take LCM of the terms and then to solve it( normal approach) .
            to make it a bit easier solve the fractions, for example-> take this case 23/7 + 91/3 = 3.3+30.3= 33.6………and now relate this answer with fraction given in the options………as 33.6 is close to 102/3….it would be hard if you take LCM of 3,7 and then solve it…….hope its clear now..

          2. ครђ

            It is the soltution of ques 7. na??

          3. Ankush Choudhary

            i told you the approach with an example, apply this in question no. 7, it would be easily solvable then……if still have problem then let me know

          4. ครђ

            ok ok got it brother :)) Thankyou so much

      1 1/4 + 2 3/4
      u can take as = 1 + 2 + 1/4 + 3/4

      1. Ab Cd

        Mam, 8 79/40 ko 9 39/40 ko kaise change krege.

      2. happy :)

        Mam, 8 79/40 ko 9 39/40 ko kaise change kiye

        1. Shubhra

          79/40 is 1 39/40 na.
          So this 1 added to 8. So becomes 9 39/40

  9. Ayushi

    mam plz give explanation of 7 ..mera ans match nhi krra

    1. 51/14 * 21/17 * 52/18 = 13
