Question

A farmer planted 1890 tomato plants in a field in rows each having 63 plants. A certain type of worm destroyed 18 plants in each row. How many plants did the worm destroy in the whole field?

Answer 1

let the number of rows=x

now,

number of plant in each row*number of rows=total number of plants

63*x=1890

x=1890/63

number of rows=30

worm destroy 18 plants in each row

so, total plants destroy by worm=18*30=540

Answer 2

Total plants, planted by farmer = 1890

Plants in each row = 63

∴ Number of rows = 1890/63=30

Worm destroys 18 plants in each row,Total plants destroys by worm = 18× 30 = 540

Hence, worm will destroy 540 plants.
