Answers:
1. (b); 2 pi.r=22
r=7/2
area=pi.r^2 =(22/7)X(7/2)X(7/2)=38.5
2. (b); (65-8)%=684
100%=1200
3. (d); L.C.M. of 8, 10, 14
Required Answer=280 second
4. (b); R=15%
CI Rate =32.25
2915.4=(PX32.25)/100
P=9040
5. (e); Required speed=360/80=4.5 m/s
6. (a); Perimeter=2(5x+4x)=18x
Distance covered by man=9X(5/18)X(3X60+36)=540
so,18x=540
x=30
Area of field=5xX4x=20x^2 =1800 m^2
7. (c); SEQUENCE=8!/3!=6720
8. (d); Let originally each children get 1 sweet
xX400=(x+1)350
x=7
9. (e);
2r=3.5
2 pi.r=3.5X(22/7)=11
10. (c); CP=8750X(100/140)=6250
