Lataben borrowed some money from a bank at a rate of 10 p.c.p.a. interest for `2 1/2` years to start a cottage industry. If she paid 10250 rupees as total interest, how much money had she borrowed?
उत्तर
Given:
Total interest (I) = 10250 rupees
Rate of interest (R) = 10%
Time (T) = `2 1/2` yrs = `5/2`
Principal (P) = ?
Formula:
Interest = `("P" xx "R" xx "T")/100`
Solution:
10250 = `("P" xx 10 xx 5/2)/100`
10250 = `("P" xx 10 xx 5)/(100 xx 2)`
P = `(10250 xx 100 xx 2)/(10 xx 5)`
P = `10250 xx 2 xx 2`
P = 10250 × 4
P = 41000
∴ Lataben borrowed ₹41000 from the bank.
