Answer 1

Answer:

72000

Step-by-step explanation:

Let P = x, r = 10%, t = 1 year.

SI = PTR/100

   = x * 10 * 1/100

  = x/10

Number of conversion period = 2 * 1 = 2.

So,

r = 10%/2 = 5%.

Then,

CI = P(1 + r/100)ⁿ - P

    = x[(1 + 5/100)² - 1]

    = (41/400)x

Now,

CI - SI = 180

=> (41/400)x - x/10 = 180

=> 41x - 40x = 72000

=> x = 72000

Therefore, sum lent out = 72000.
