उत्तर
Let the value of monthly instalment be Rs. x
Maturity value (M.V.) = Rs. 8,088
Period = n = 3 years = 36 months
Rate of interest = r = 8% p.a.
∴ `S.I. = P xx (n(n+1))/(2xx12) xx r/100`
= `x xx (36 xx 37)/24 xx 8/100`
= `444/100x`
= 4.44x
Total amount of maturity = 36x + 4.44x
`\implies` 8088 = 40.44x
`\implies` x = 200
Thus, the value of monthly instalment is Rs. 200.
