EXPLANATIONS

1. (75/315) × 100 = 23.8 » 24

2.  Average Sales = (45+80+40+75)/5=29500/5=  5900

3.  75 : 80 = 15 : 16

6. Increment % =

7. Average appeared = (20 + 22.5 + 17.5 + 27.5 + 25 + 35 + 27.5)/7= 175/7  = 25

8. Required Ratio = 32.5 : 22.5 = 13 : 9

9.

10. Number of students enrolled in 2010 & 2013 = 2500 + 3750 = 6250
Number of students appeared in 2008 & 2014 = 2000 + 2750 = 4750
Difference = 6250 − 4750 = 1500

11. Average price = (22.5 + 25 + 40 + 15 + 30 + 35)/6 = 27.92 Rs

12. Total value = Quantity sold × Rate per kg
Total value of item B = 1750 × Rs.25 = Rs.43,750
Total value of item E = 2750 × Rs.30 = Rs.82,500
Required Difference = 82500 − 43750 = Rs.38,750

13. Value of A = 3000 kg × Rs.22.5 = Rs.67,500
Value of D = 3500 × 15 =  Rs.52,500
Required Ratio = 67500 : 52500 = 9 : 7

14. Total value of F = 1500 × Rs.35 = Rs.52,500
Total value of C = 2500 × Rs.40 = Rs.1,00,000
Required% = (52500/100000)*100 = 52.5%

15. Quantity sold by B after 20% increment = 120% of 1750 = 2100 kg
Price after 10% reduction = 90% of 25 = Rs.22.5
Value = 2100 × 22.5 = Rs.47,250

16. Required Difference = 60000 − 40000 = 20000 tonnes

17.
