Step-by-step explanation:Given that:

  • Sum = Rs 1200
  • Amount = Rs 1800
  • Rate of interest = 5% per annum

To Find:

  • Time

Formula used:

  • SI = A - P
  • SI = (P × R × T)/100

Where,

  • SI = Simple interest
  • A = Amount
  • P = Sum/Principal
  • R = Rate of interest
  • T = Time

First we have to find simple interest:

⇒ SI = A - P

⇒ SI = Rs 1800 - Rs 1200

⇒ SI = Rs 600

∴ Simple interest = Rs 600

Now finding the time:

⇒ SI = (P × R × T)/100

⇒ 600 = (1200 × 5 × T)/100

⇒ 600 = 6000T/100

⇒ 600 = 60T

⇒ T = 600/60

⇒ T = 10
