    7800
    8520
    9844
    6100
    8148
    Option E
    9898 + 1073 – 1882 × 3 ÷ 2 = ?
    10971 – 941*3 = ?
    => ? = 8148

     

  4. √1225 / 3√343 * 45% of 760 = ?
    1700
    1010
    1220
    1550
    1710
    Option E
    √1225 / 3√343 * 45% of 760 = ?
    => 35/7 * 342 = ?
    => ? = 1710

     

  5. 3(1/7) + 2(3/5) + 7(1/5) – 5(3/7) – 18/35 = 35/?
    8
    5
    9
    7
    6
    Option B
    3(1/7) + 2(3/5) + 7(1/5) – 5(3/7) – 18/35 = 35/?
    => 35/? = 22/7 + 13/5 + 36/5 – 38/7 – 18/35 = 245/35
    => ? = 5

     

  6. If ratio of investment A, B and C are in the ratio 3 : 5 : 8 and the time of investment of A, B and C are 100/3 %, 80% and 25% respectively of their investment, and profit of A is 4800 then what will be the profit of C.
    55000
    41100
    35500
    25600
    22100
    Option D
    Ratio of profit = 3×3× 1/3 : 5×5× 4/5 ∶ 8×8× 1/4
    = 3 ∶ 20 ∶ 16
    Profit of C = 4800/3 ×16 = 25600

     

  7. Cost price of 3 pens is equal to the cost price of 5 pencils. If equal number of pens and pencils are sold and pens are sold at 20% profit and pencils are sold at 100/3 % profit then what is the overall profit percentage.
    27%
    30%
    25%
    15%
    20%
    Option C
    Let 15 pens and 15 pencils are sold and cost of 1 pen is Rs.10
    So, Cost of 3 pen is Rs.30 which is equal to cost of 5 pencils.
    Total cost priceof 15 pens and 15 pencils = 15 × 10 + 6 × 15 = 150 + 90 = Rs.240
    Total selling prices of 15 pens and 15 pencils = 150× 6/5 + 90× 4/3 = 180 + 120 = 300
    Overall percentage profit = [300 – 240]/240 ×100
    = 60/240 ×100 = 25%

     

  8. If the volume and curved surface area of a cylinder 616 m3 and 352m2 respectively, what is the total surface area of the cylinder (in m^2 )?
    510 m^2
    321 m^2
    429 m^2
    525 m^2
    400 m^2
    Option C
    𝜋𝑟^2ℎ/2𝜋𝑟ℎ = 616/352
    𝑟 = 3.5 m
    𝜋𝑟^2ℎ = 616
    ℎ = 616/11×3.5 = 16 m
    Total S.A. = 2𝜋𝑟ℎ + 2𝜋𝑟^2 = 2𝜋𝑟(ℎ + 𝑟)
    = 2× 22/7 ×3.5(3.5 + 16) = 429 m^2

     

  9. The strength of a school increases and decreases in every alternate year by 10%. It started in 2000 and increases in 2001, then the strength of the school in 2003 as compared to that in 2000 was:
    Increase by 7.7%
    Increase by 7.0%
    Decrease by 7.7%
    Increase by 8.9%
    Decrease by 8.9%
    Option D
    Let in 2000, the strength was 100.
    In 2001 strength = 110
    In 2002 strength = 110 × 90/100
    In 2003 strength = 110 × 90/100 × 110/100 = 108.9
    Required % increment = 8.9%
    Hence, strength after 3 years will increase by 8.9%

     

  10. In how many ways can 5 different toys be packed in 3 identical boxes such that no box is empty, if any of the boxes may hold all of the toys ?
    35 ways
    25 ways
    30 ways
    15 ways
    20 ways
    Option B
    Case 1: 5C2*3C2 = 15 ways
    Case 2: 5C3 = 10 = 10 ways.
    Required ways = 25 ways
