उत्तर
Given:
Time period: n = 4 years = 48 months
Rate of interest: r = 10% p.a.
Interest received on maturity: ₹ 6370
`I = (Pxxn(n+1)xxr)/(2xx12xx100)`
`=( Pxx48xx49xx10)/2400 = ₹6370`
`Pxx23520/2400=6370`
`=> P = (6370xx2400)/23520 `
= ₹ 650
Total deposit:
P ⋅ n
= 650 ⋅ 48
= ₹ 31200
Maturity value:
MV = ₹ 31200 + ₹ 6370
= ₹ 37570
