C) 6 women, 2 men and 12 children
D) 4women, 2 men and 14 children
Ans. B
Suppose for men x, women y & children z,
3x+2y+0.5z=20
x=1,y=5,z=14
On looking into options,
1.90-11*2 = 68,
2.90-12*2=66,
3.90-14*2=62,
4.90-10*2=70,
from this only 68 is divisible by 4 ,hence Ans. is 11

Q.3 A parcel weighing 12 kg is to be sent from New Delhi to Mumbai a distance of 1450 km.
The Parcel Postage Rates are shown in the following table:
Distance Category Rate upto to 2 kg INR For every additional kg over 2 kg INR
Local 35 5
Upto 500 km 50 8
501 to 1000 km 60 12
10001 to 2000 km 70 25
More than 2000 km 90 35
How much will it cost to send the parcel ?
A) 85 INR
B) 95 INR
C) 320 INR
D) 840 INR
Ans. C
Weight of the parcel sent
from New Delhi to Mumbai = 12 kg
Distance between New Delhi and Mumbai = 1450 km
Q.4 This distance lies in the distance category 1001-2000 km. So, the cost to send 12 kg parcel would be the cost of sending a 2 kg parcel at Rs 70 plus the cost for every additional kg over 2 kg i.e. at
Rs 25 /kg.
Thus, cost of sending the parcel = Rs 70 + (12
–
2) kg × Rs 25/kg = Rs 70 + Rs 10 × 25 = Rs 320
