Answers
Answers
1 (b); Since Average of A, B, C & D=25
so, number are 22, 24, 26, 28
Required Answer=22X28=616
2. (a); Required %=(72+68+62+74+64)/400=85%
3. (b); Amla's monthly income=4/5X429600X1/12
Amla's Annual income=4/5X429600=343680
4. (e); 45% of x+20% of x=4056
85% of x=(4056/65)X85=5304
5. (c); Let Madhur's age=x
& satish age=4x
4x+8=2.5(x+8)
x=8
AGe of Madhur's age after another 8 years=8+16=24
Age of Satish age after another 8 years=32+16=48
6. (d)x^3 = 1728
x = 12
7. (c)128 = (100X8XR)/100
R = 16
8. (a);CP=7200X(100/80)
SP=7200X(100/80)X(120/100)=10800
9. (e); Required Height=4X170-3X172
=688-516=172
