Question

interest, interest being payable half-yearly?
In a factory the production of machines rose to 48400 from 40000 at 10% p.a. Find the time period.​

Answer 1

Answer:

The production of cycles rose to 48,400 from 40,000 in 2 years

⇒ Present production = 40,000

⇒ After two years = 48,000

⇒ Time = 2 years

⇒ Rate of increasement = ?

According to the question,

Production after 2 years

= Present production(1+R100)t

⇒48,400 = 40,0000 (1+R1002)

⇒484400=(1+R100)2

⇒1+R1002220

⇒R100=110

⇒R=10%

⇒Rate of increasement = 10%
