Simple interest = (sum x rate of interest x time period in months ÷ (100 x 12) So, simple interest earned = 50000 x 40 x 42 ÷ (100 x 12) = Rs. 70,000 So, amount after 42 months = 50000 + 70000 = Rs. 1,20,000 Hence, option b.
In each of these questions, two equations (I) and (II) are given.You have to solve both the equations and give answer
I. x² - 8x + 15 = 0 ...
I). p2 + 16p + 55 = 0
II). q2 + 9q + 20 = 0
Solve the quadratic equations and determine the relation between x and y:
Equation 1: x² - 21x + 110 = 0
Equation 2: y² - 23y + 132 = 0
I. y² - 7 y – 18 = 0
II. x² + 10 x + 16 = 0
