Where am I doing wrong?

Anoop deposited a certain amount at 15% p.a simple interest in the name of his son when his son was 6 years old. It became 37,240/- when his son turned 12 years of age. What was the amount he deposited initially?

Ans) R = 15%

I = 37240

T = 6 years

SI = P * R * T/ 100

37240 = (P * 15 * 6 )/ 100

P = 37240 * 100/15 * 6

P = 41377.7

But answer is 19,600. How?

Should be: 37240 = P + (P * 15 * 6)/100
