Distance = Speed * Time

Time = t

Distance = x

60 * t = (60 â€“ 10) * (t + 1)

60t = 50t + 50

t = 5

Distance = 60 * 5 = 300 km

20 boys complete the work = 1/15

40 boys complete the work = 2/15 = 1/7.5

15 girls complete the work = 1/12

20 girls complete the work = 20/(15 * 12) = 1/9 days

20 girls and 40 boys together can complete the work = 1/7.5 + 1/9

= 16.5/67.5

Required time = 67.5/16.5 = 4 1/11 days

Side of the square = 56/4 = 14 cm

Radius of the circle = 14/2 = 7 cm

Circumference of the circle = 2Ï€r = 2 * 22/7 * 7 = 44 cm

Perimeter of the rectangle = 2 * (l + b) = 44 cm

2 * (8x + 3x) = 44

11x = 22

x = 2 cm

Length of the rectangle = 8 * 2 = 16 cm

Breadth of the rectangle = 3 * 2= 6 cm

Area of the rectangle = 16 * 6 = 96 cm2

CP = x

MP = x * 125/100 = 5x/4

SP = 5x/4 * 85/100 = 17x/16

17x/16 â€“ x = 250

x/16 = 250

x = 4000

Profit will be shared in ratio = (2 * 12): (5 * 120/100 * 5): (4 * 12)

= 24 : 30 : 48

= 4: 5: 8

Râ€™s profit = 25450/5 * 8 = Rs.40720
