लिखित उत्तर

Verified by Experts

(d) Let the time is 't' years and the rate of interest is R% (माना की t वर्ष के बढ़ राशि बराबर हो जाएगी)
According to the question
Case (I):y=`(x xxRxxt)/(100)….(i)`
Case(II):z =`(yxxRxxt)/(100)…(ii)`
By dividing eqyation (i) by equation(ii)
`(y)/(z)=(x xxRxxt)/(yxxRxxt) Rightarrow y^(2)=zx`
