   305
   300
   341
   380
   330
   Option D
   18 ×? = 6367 + 333 + 140
   18 ×?= 6840
   ? = 6840/18 = 380

    

2. 87.5% of 3888 – 462 × 6 = ? % of 4200

   Option E
   87.5% of 3888 – 462 × 6 = ? % of 4200
   3402–2772 = x/100 × 4200
   630 = 42x
   x = 15

    

3. 675/27 + 112 × 1.5 – 35% of 420 = ?
   52
   46
   25
   32
   40
   Option B
   675 27 + 112 × 1.5 – 35% of 420 = ?
   = 25 + 168 – 147 = 46

    

4. 104832 ÷ ? = 64 × 42
   20
   23
   39
   40
   38
   Option C
   104832 ÷ ? = 64 × 42
   = 104832/64×42 = 39

   390
   450
   444
   353

   Rs.8000
   Rs.6000
   Rs.6500
   Rs.7500
   Rs.7000
   Option D
   45000*(100/120) = 37500
   GST = 45000 – 37500 = Rs.7500

    

7. A train crosses a 300 m long platform at a speed of 72kmph in 25 sec and also passes a second train 250 m long running in opposite direction towards each other in 15 sec. what is the speed of the second train?
   36 kmph
   33 kmph
   42 kmph
   30 kmph
   26 kmph
   Option A
   Let the length of first train be l1.
   (l1 + 300)/ 72 × 5/18 = 25
   l1 + 300 = 500 𝑙1 = 200 m
   Given, (250 + 200)/ 72 × 5/18 + 𝑥 = 15
   450/(20 + 𝑥) = 15 30 = 20 + x
   x = 10m/s
   x = 10 × 18/5 = 36 kmph

    

8. A water tank normally takes 7 hours to be filled by a tap but because of the leak, it takes another 2 hours. In how many hours will the leak empty a full water tank?
   50.1 hours
   45.5 hours
   11.5 hours
   31.5 hours
   21.5 hours

   Required time = 1/7 – 1/9 = (9−7)/ 63
   = 2/63 = 31.5 hours

   80%
   50%
   100%
   60%
   70%
   Option C
   Principal = Rs.400
   Amount = Rs 100 x 6 = Rs 600
   Interest = Rs 600 – Rs 400 = Rs 200
   Time = 6 months = 6/12 years
   Now, 200 = 400 × 1 × r/ 2 × 100
   r = 400 × 100/ 400 = 100%

    

10. Two dice are thrown simultaneously. What is the probability of getting the sum of the numbers as even?
    1/5
    1/3
    1/2
    1/4
    1/7
    Option C
    Throw two dice n(s) = 36
    E is nos sum is even.
    Hence E={( 1,1 ),(1,3 ) (1,5 ) (2,2 ) , (2,4 ) , (2,6 ), …………( 6,2 ), (6,4 ), ( 6,6 )}
    n(E)= 18
    Required probability = 18/36 = 1/2
