Solution Key:

1). D; area of equilateral ∆ = √3/4×x²

where, ( x = side)

√3/4×x² = 9√3

àx = 6 cm.

àarea of circle = πr² , (where, r = x)

π× 6² = 113.04

2). C; √ (12²+4²+3²) = 13m

3). D; h:d = 2:3 àh:2r = 2:3

àh/12 = 2/3 = 8

àVolume/C.S.A = (πr²h)/(2πrh)

à6/2 = 3/1 or 3:1

4). C; (1500×1200×10)/(24×25×10) = 3000

Since 1/3 rd is built, so required bricks = (2/3) × 3000 = 2000

5). B; As 2 days work = (1/20) × 2 = 1/10

à(A+B+C) 1 day = 1/20 + 1/30 + 1/60= 1/10

àwork in 3 days = 1/10 + 1/10 = 1/5

àso 1/5 work is done in 3 days,

àso can be finished in 3 × 5=15 days.

6). B; Total Balls = 2+3+2 = 7

à2 balls drawn should not be blue à except blue, total is 5, so ⁵c₂ out of total ⁷C₂

àso required probability = (⁵c₂)/( ⁷C₂) = 10/21

7). C; Let CP = Rs. 100, àP = Rs. 320,

:. SP = Rs. 420 à New CP = Rs. 125,

àSP = Rs. 420, àP = 420 - 125 = 295

àP % (295/420) ×100=70% (Profit % of SP)

8). D; 5! = 1× 2× 3× 4×5 = 120

9). B; Valid votes = 80% of 7500 = 6000

2^nd candidates got = 45% of 6000 = 2700

10). E; Maximum marks is not given.
