ans: 720 per week
step by step :
let ,the amount earn per week =x
the ratio of amount earn per week = 720 : x
number of days is inversely proportion to the number of hours each man work per days and number of men at work
720 : x = 8*6 : 6*8
720/x. =8*6/6*8
720/x = 1
x = 720 per week

The correct answer was given: Brain
Given,
internal diameter=24cm
internal radius=24/2=12cm
external diameter=25 cm
external radius =25/2=12.5cm
surface area of internal bowl=2πr²
=2(22/7)(12²)
=2×22×12×12/7
=905.14cm²
surface area of external bowl=2πr²
=2(22/7)(12.5²)
=2×22×12.5×12.5/7
=982.14cm²
surface area of ring=π(r²-r²)
=22/7(12.5²-12²)
=22/7(12.25)
=22×12.25/7
=38.5cm²
cost of internal bowl=905.14×0.05=rs.45.25
cost of external bowl=982.14×0.05=rs.49.1
cost of ring=38.5×0.05=rs.1.925
cost of bowl=45.25+49.1+1.9=96.25 rupees approx
i it is correct answer
=[(8a^3x64a^3x2)/3^8]/3
=1024a^3/3^9
=(32a)^3/27^3
=(32a/27)^3
