1.	a sum of money lant at simple intrest amount to rs 3224 in 2 years and rs 4160 in 5 years find the sum and the rate of intrest
Answer» Hi BRO .Nice Quesion.Step-by-step explanation:Amount in 5 YEARS = (principal SI for 5 years) =Rs4160. Amount in 2 years = (principal SI for 2 years) = 3224. On subtracting we get : SI for 3 years = Rs(4160−3224) = Rs936. Or SI for 2 years = Rs(936x2/3) = Rs624. Or sum = (amount for 2 years) - (SI for 2 years) = Rs(3224−624) = Rs2600. Now, principal = 2600, SI=Rs624, time=2years. Therefore, rate =(100xSI)/(PxT)= (100x624)/(2600x2)% =12%p.a. PLEASE MARK ME AS BRAINLEST
