18 majdoor kisi divar ko 15 din me 90 metre banate hai to 20 majdoor usi divar ko 12 din me kitne metre banayenge​

Answer 1

Answer:

80 metre

Step-by-step explanation:

majdoor × din = deevar

majdoor1 :majdoor2 :: din1 :din2=deevar1 :deevar2

18 : 20 : : 15 : 12 = 90 : x

18 × 15 : 20 × 12 = 90 : x

270 : 240 = 90 : x

9 : 8 = 90 : x

9 × x = 8 × 90

x = 8 × 90 / 9

x = 80 metre
