Question

In 2001 the production of sugar is 1584 million kgs which is 20% less than that in 1991. Find the production (in million kgs) of sugar in 1991.

Answer 1

let production in 1991 be 'x'

In 2001 it is 20% less than in 1991,

x-(20%x)

x-(20/100)x

x-0.2x

0.8x in 2001

given in 2001 it is1584 million kg

hence,

0.8x=1584

x=1980 million kg
