If how many years will Rs 3000 become Rs 4234 at 9% P. A CI?

1year, 3 months

Step-by-step explanation:

According to the question,

Principle = Rs 3000

Amount = Rs 4234

Rate = 9% = 9/100 = 0.09

Time = n.

From the Formula:

P( 1 + r )ⁿ = A

A => P ( 1 + r)ⁿ

A=> 3000( 1 + 0.09 )ⁿ

4234=> 3000 ( 1 + 0.09 )ⁿ

Divide both sides by 3000

1.41 = (1.09)ⁿ

Divide both sides by 1.09

n = 1.29 approximately 1.3

Therefore, a sum of Rs.3000 amount to Rs.4234 at 9% pa compounded annually in 1 year, 3 months.

I hope this helps.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

the answer will be the last one
