Answer:
10.5%
Step-by-step explanation:
Principal=p
( P/4, Remaining=3p/4)
p[1+10/100]^2=p/4[1+10/100]^2+[3p*2*r/4*100+3p/4]
Cancel p on both sides
[1+10/100]^2-1/4[1+10/100]^2=3*2*r/4*100+3/4
3/4[1+10/100]^2=3/4[2r/100+1]
Cancel 3/4 on both sides
121/100=2r+100/100
Cancel 100 on both sides
121-100=2r
2r=21=10.5
