Question

what is mean by direct and inverse variation

Answer 1

Direct Variation - when both the quantities such as work and time or something else are in same for increasing ....both are increasing or both are decreasing is said to be Direct Variation...
for example - 12 oranges cost 50 so 18 oranges will cost 100 so hence the oranges are increasing its cost is also increasing so its in direct variation..

Inverse Variation It is inverse of direct variation such as......one quantity is increasing and other is decreasing it is said to be in inverse Variation ....for eg u can take ...5 men's do a work in 8 hours so 10 men's will do in 5 hours hence the men's are increasing and the time is decreasing...its in Inverse Variation..
