say value of with collateral loan = X
value of without collateral loan = y
now without collateral loan accounts for 60% of total
and we know number of loans without collateral are 2 and with collateral are 3
so, 2y = (3/5) (3x+2y)
by solving we get, y= (9x/4)
we need to find, how much percent y is bigger than x
y = (100+p/100) x
9x/4 = (100+p/100) x
900 = 400 + 4p
500 = 4p
p = 125%
