Question

8.If by decreasing one quantity the other also decreases then they are in ?(a) inverse proportion(b) direct proportion(c) zero proportion(d) none​

Answer 1

Answer:

if by decreasing on quality intinti The other also decreases then they are in inverse proportion direct operation operation

Answer 2

If by decreasing one quantity the other also decreases then they are in direct proportion.

Direct proportion - two values are said to be in direct proportion when an increase in one value results in the increase in the other value and vice versa.

Example: y = kx

where k is an independent term.

here y ∝ x

Indirect proportion - two values are said to be in indirect proportion when an increase in one value results in the decrease in the other value and vice versa.

Example: y = k/x

here y ∝ 1/x

Zero proportion - two values are said to be in zero proportion when an increase or decrease in one value doesn't result in increase of decrease in the other value.

Example: y = km, x = ln

where, m and n are variables

k and l are the constants

y and x are independent of each other.
