Answer:

Rs.252.20

Step-by-step explanation:

Principal (P) = Rs.1600

Rate (R) = 10% p.a.

Time (T) = 1½ years = 3/2 years

Amount (A) = P × (1 + R/100)ⁿ

=> A = 1600 × (1 + 10/200)³

=> A = 1600 × (21/20)³

=> A = Rs.1852.20

Hence, C.I. = Rs.(1852.20 - 1600) = Rs.252.20

Hope it helps!! Mark this answer as brainliest if u found it useful and follow me for quick and accurate answers...

Step-by-step explanation:

initial amount , P = 16000

rate of interest per annum , r = 10%

time, n =( 1 1/2) × 2 = 3 half years .

using formula, C.I = P(1 + r/200)ⁿ - P

= 16000(1 + 10/200)³ - 16000

= 16000[(1 + 1/20)³ - 1]

= 16000[1 + 1/20³ + 3(1/20)(1 + 1/20) - 1 ]

= 16000[1/8000 + 3/20 × 21/20 ]

= 16000 [1/8000 + 63/400 ]

= 16000 [1/8000 + 1260/8000]

= 16000 × 1261/8000

= 2 × 1261

= 2522
