Question

Table 1 shows the height and growth of two friends for a year.

Kamal = Height:145 cm Growth: 30%

Salman = Height: 140 cm Growth: 35%

By applying the concept of proportion, who is more higher after a year? Justify your choice.

Answer 1

Kamal: $145\cdot(1+0.3)=188.5$ cm.

Salmah: $140\cdot(1+0.35)=189$ cm.

$$189>188.5$$

 Salmah is more higher after a year.
