Solution :
(i) Total amount Mr Prateek has =Rs. 15000 Amount spent on child's education = 35% of \[15000==\frac{35}{100}\times 15000=Rs.5250\] So, amount saved by him \[=Rs.\,(15000-5250)=Rs.\,9750\] (ii) Aggregate marks \[=65+75+65+82+91=378\] Maximum marks for five subjects \[=100\text{ }\times 5=500\] Percentage of aggregate marks \[=\frac{378}{500}\times 100=75.6%\] (iii) C.P. of \[100\times 12\] pencils \[=Rs.\,(20\times 100)\] \[=Rs.\,2000\] S.P. of 1 pencil = Rs. 2 S.P. of \[100\times 12\]pencils \[=Rs.\,(20\times 100)\] \[=Rs.\,2400\] Profit \[=S.P.-C.P.=Rs.\,(2400-2000)=Rs.400\] Profit % \[=\frac{400}{2000}\times 100=20%\]
