1.	Thenmozhi’s height is 1.25 m now. She grows for 5 cm every year. What would be her height after 6 years?
Answer» Thenmozhi’s present height = 1.25 m Rate of growth per year = 5 cm Her growth in 6 years = 5 cm × 6 = 30 cm. After 6 years her height = 1.25 m + 30 cm = 1.25 × 100 + 30 cm = 125 + 30 cm = 155 cm. ∴ After 6 years Thenmozhi’s height will be 155 cm.

Thenmozhi’s height is 1.25 m now. She grows for 5 cm every year. What would be her height after 6 years?

Answer»

Thenmozhi’s present height = 1.25 m

Rate of growth per year = 5 cm

Her growth in 6 years = 5 cm × 6 = 30 cm.

After 6 years her height = 1.25 m + 30 cm

= 1.25 × 100 + 30 cm

= 125 + 30 cm

= 155 cm.

∴ After 6 years Thenmozhi’s height will be 155 cm.
