1)d   2)b   3)a   4)b   5)b   6)d   7)d   8)a   9)c   10)e

Solution:
1). Marked price = 11250 × 10/9 = Rs. 12500
Total cost=12500 + 150 + 800=Rs. 13450
S.P = 13450 × 115/100 = Rs. 15467.50

2). % profit = Loss/Actual Weight x 100
= 500 – 425/500 × 100
= 75/500 x 100 = 15%

3). Perimeter of plot = 3300/15 = 220 meter
2πr = 220
2 × 22/7 × r = 220
r = 35 m.
Area of plot = πr^2
= 22/7 × 35 × 35 = 3850 mt^2
Cost of flooring = 3850 × 100=Rs. 385000

4). Suppose Ashwin lend Rs. x to Ramesh then,
Xx16x3/100 - (X – 6300) × 14 × 3/100 = 618......(1)
From equation I ,
x = Rs. 6800

5). Total interest
= 20000 × 110/100 × 110/100 × 120/100 - 20000
= 29040 - 20000= Rs. 9040

6). Cannot be determined

7). Total wages of a factory
=450 x 45= Rs. 20250/
Total wages of another factory
= 340 x 60
= Rs. 20400
Total average = 20250 + 20400/450 + 340
= 40650/790
= 51.46 = Rs. 51

8). Total ways = 4 ! x 2 !
= 4 × 3 × 2 x 2= 48

9). 1 man = 2 women
8 men + 4 women = 20 women
2 day's work of 20 women = 20 × 6/1
= 20 × 2/x
x =1/3
Remaining work = 1 – 1/3 = 2/3
Total number of females = 16
20 × 6/1 = 16 × x ÷2/ 3
x = 5 days
Short Cut
M1D1=M2D2+M3D3
10x6 =10x2 + 8 x
60-20= 8x
x= 5 days

10). x + 300% of x / y +150% of y = 3/5
400x/250y = 3/5
x/y = 3 × 250 /5 × 400
x/y = 3/8
