Answer:

Answer Is 9282.

Step By step Explanation=

Given:

Given:P = 2000

Given:P = 2000t = 2 years

Given:P = 2000t = 2 yearsr = 20%

Given:P = 2000t = 2 yearsr = 20%Concept used :

Given:P = 2000t = 2 yearsr = 20%Concept used :Amount = P[1 + (R/100)]T

Given:P = 2000t = 2 yearsr = 20%Concept used :Amount = P[1 + (R/100)]TWhen compounded half-yearly,

Given:P = 2000t = 2 yearsr = 20%Concept used :Amount = P[1 + (R/100)]TWhen compounded half-yearly,T = 2 × T

Given:P = 2000t = 2 yearsr = 20%Concept used :Amount = P[1 + (R/100)]TWhen compounded half-yearly,T = 2 × T R = R/2

Given:P = 2000t = 2 yearsr = 20%Concept used :Amount = P[1 + (R/100)]TWhen compounded half-yearly,T = 2 × T R = R/2CI = A - P

Given:P = 2000t = 2 yearsr = 20%Concept used :Amount = P[1 + (R/100)]TWhen compounded half-yearly,T = 2 × T R = R/2CI = A - PCalculation:

Given:P = 2000t = 2 yearsr = 20%Concept used :Amount = P[1 + (R/100)]TWhen compounded half-yearly,T = 2 × T R = R/2CI = A - PCalculation:If interest compounded half-yearly, then

Given:P = 2000t = 2 yearsr = 20%Concept used :Amount = P[1 + (R/100)]TWhen compounded half-yearly,T = 2 × T R = R/2CI = A - PCalculation:If interest compounded half-yearly, thenT= 2 × 2 = 4

Given:P = 2000t = 2 yearsr = 20%Concept used :Amount = P[1 + (R/100)]TWhen compounded half-yearly,T = 2 × T R = R/2CI = A - PCalculation:If interest compounded half-yearly, thenT= 2 × 2 = 4R = 20/2 = 10%

Given:P = 2000t = 2 yearsr = 20%Concept used :Amount = P[1 + (R/100)]TWhen compounded half-yearly,T = 2 × T R = R/2CI = A - PCalculation:If interest compounded half-yearly, thenT= 2 × 2 = 4R = 20/2 = 10%A = 20000 × (11/10) × (11/10) × (11/10) × (11/10)

Given:P = 2000t = 2 yearsr = 20%Concept used :Amount = P[1 + (R/100)]TWhen compounded half-yearly,T = 2 × T R = R/2CI = A - PCalculation:If interest compounded half-yearly, thenT= 2 × 2 = 4R = 20/2 = 10%A = 20000 × (11/10) × (11/10) × (11/10) × (11/10)⇒ A = 29282

Given:P = 2000t = 2 yearsr = 20%Concept used :Amount = P[1 + (R/100)]TWhen compounded half-yearly,T = 2 × T R = R/2CI = A - PCalculation:If interest compounded half-yearly, thenT= 2 × 2 = 4R = 20/2 = 10%A = 20000 × (11/10) × (11/10) × (11/10) × (11/10)⇒ A = 29282CI = 29282 – 20000

Given:P = 2000t = 2 yearsr = 20%Concept used :Amount = P[1 + (R/100)]TWhen compounded half-yearly,T = 2 × T R = R/2CI = A - PCalculation:If interest compounded half-yearly, thenT= 2 × 2 = 4R = 20/2 = 10%A = 20000 × (11/10) × (11/10) × (11/10) × (11/10)⇒ A = 29282CI = 29282 – 20000⇒ CI = Rs. 9282

Given:P = 2000t = 2 yearsr = 20%Concept used :Amount = P[1 + (R/100)]TWhen compounded half-yearly,T = 2 × T R = R/2CI = A - PCalculation:If interest compounded half-yearly, thenT= 2 × 2 = 4R = 20/2 = 10%A = 20000 × (11/10) × (11/10) × (11/10) × (11/10)⇒ A = 29282CI = 29282 – 20000⇒ CI = Rs. 9282∴ CI is Rs 9282.
