You ask your best friend to lend you ₹400 to buy your favourite toy. he says that he can lend you the money only if you give him an extra ₹10 for every six months that pass before you return it.

You didnt ask a question

Step-by-step explanation:

The question is whether I should pay my best friend 10 on a 400 loan every six months . That is 20 a year or 5 percent a year interest of 400 . That is reasonable to both sides .To remain friends , both sides should benefit.  Friends are like day and night ,they  come and they go . The object is to make them meaningful .Just like in business and family .What  would you do with 400 for six months to make more than 10  ?

Step-by-step explanation:Reasonableness to both sides creats truth . Men lie ,women lie , numbers tell the truth universally . The Truth is the first chapter in the book of Wisdom.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
