filledbookmark USE APP Sign in Questions & Answers CBSE Mathematics Grade 7 Simple Interest Answer If Rs. 10000 is invested at 5% interest rate p.a. Find the interest at the end of the one year. Answer VerifiedVerified 181.7k+ views 4 likes Hint: In this problem, we need to find the interest at the end of one year using a simple interest formula. Complete step-by-step answer: The formula for simple interest is shown below. Simple interest = P⋅r⋅t100......(1) Here, P is principal, r is rate of interest and t is time in years. Substitute 10000 for P , 5 for r and 1 for t in equation (1) to obtain the interest at the end of one year. Simple interest = (10000)⋅(5)⋅(1)100⇒Simple interest = 50000100⇒Simple interest = 500 Thus, the interest at the end of the one year is Rs.500.

If the mean of 5 consecutive multiples of 3 is 12.find the sum of 3rd and 4 th number.

Preeti Dabral 2 years, 3 months ago

Let x be smallest number. Then the 5 numbers are x, x+3, x+6, x+9 and x+12.

Given that mean is 12.

(x + x+3 + x+6 + x+9 + x+12) / 5 = 12

5x + 30 = 12 × 5

5x = 60 - 30

5x = 30

x = 30/5

x = 6

Hence, sum of 3rd and 4th no is

x+6 + x+9 = 2x + 15

x+6 + x+9 = 2×6 + 15

x+6 + x+9 = 27

Hence, the sum of 3rd and 4th number is 27.
