ANSWERS WITH SOLUTION : 

1. (4)

Required no. of passengers

=1/3[(24+20+15) % of 8500]

= (1*8500*59)/100*3 = 1671

2. (1)

Number of passenger in train - R  = (8500*9)/100 = 765

Number of males = (100-34-26) % of 765

= (765*40)/100 = 306

3. (5)

 Reqd% = (19) / ( 13 + 9 ) x 100 =86  ( approx)

4. (3) :

It is clear from the pie chart.

5. (4)

Reqd.% = [(20-15)/15]*100 = 33(approxi)

6. (5)

Number of L types products sold by Store F=48
by Store E=40
Required percentage= (48) / (40) x 100 = 120

7. (5)

Reqd. ratio = (61+54) : (54+48)

=115:102

8.  (2) 

Average price = Rs (16+15+14.5+16+18+15)/6*1000 = 15750

9.  (1) 

Reqd. difference = (60*75-44*15)*1000 = (4500-660)*1000 = Rs = 38.4 lakhs

10. (4)
