The formula is

We have:


Substituting these values into the formula, we have


⇒ divide each term by 16

⇒ find the pair of numbers that multiply to give 4 and sum gives -5 which is -1 and -4

⇒ We have two values of t

⇒


⇒

Answer:
first
Step-by-step explanation:
Answer:
1 : 6
Step-by-step explanation:
3 : 18
3 ÷ 3 : 18 ÷ 3
1 : 18 ÷ 3
1 : 6
Step-by-step explanation:
WE know
- A=P(1+r/n)^nt, where A is the amount, P is the principle r is the rate , t is the time and n is the number of interest compounded per unit time
so by suing this formula
- A=40000(1+0.1/2)^2*2
- A=40000(1.2155)
- or, A=48620.25
- therefore the amount is Rs.48620.25
