Answers With
Explanation:-

1. (4)
Average Speed = (2 * 40 * 50)/90 = 44.444 km/hr

2. (4)
Required price = 39 * 1.1/1.3 = 33

3. (1)
Let the numbers be 2x and 3x.
6×2 = 54
x = 3
Sum of numbers = 5x = 15

4. (4)
Let the total number of pages be x.
x – x/3 – x/6 = 75
x = 150

5. (1)
P can finish the job in = 3/2 of 8 = 12 days
SO Q will take 12/2 = 6 days to finish the job.

6. (4)
Daily  wages are in the ratio 3 : 4 : 5 ,
working days of A,B,C = 8,9 and 12 so the wages they get will be in ratio 24 :
45 : 48,

Share of C = 48/(24+45+48) × 1950 = Rs 800

7. (2)

use
chain rule ; if 100 men will do one job in 100 days individually , so one man
will do one job in 100 days .

8. (4)
C.P. of one mango = 12/15 = 80 paise ; S.P. of
one mango = 15/12=Rs 1.25 ;

Gain = 45 paise , gain = 45/80 × 100 = 56.25 %

9. (1)

average
speed = (2x×y )/((x+y))=(2 × 50 × 60)/(50 + 60) = 600/11 = 54 6/11 km/hr

10. (2)
value of (90% – 83%)x = 175, 7% of x = 175, 100
% = 2500

99 % of 2500 = 2475

  1. Daily wages are in the ratio 3 : 5 : 4 ,
    working days of A,B,C = 8,9 and 12
    so the wages they get will be in ratio
    (3*8):(5*9):(4*12)
    =24 : 45 : 48
    =8:15:16,
    Share of C =1950*16/(8+15+16)
    =1950*16/39
    = Rs 800
