Question

if 3/5of a plot of land questions 75120 what will 7/20 of the plot cost

Answer 1

Cost of 3/5 = 75120
Cost of 1 = 75120 * 5/3

Now cost of 7/20 = 75120 * 5/3 * 7/20
= 75120 * 35/60
= 43820

Answer 2

let land cost=x
3/5 × x = 75120
x= 75120×5/3
x=25040×5
x= 125200
7/20 ×x
7/20× 125200
7/2 × 12520
7×6260
= 43820 is answer
