**Solutions of ICSE Maths Specimen Paper -2021 **

**Ans-1**

(a)

Principal (n)= 2.5 year= 2.5*12 month=30 months

Principal (P)= Rs 600

Rate = 10% p.a.

Maturity Value= ……………

S.I.= P*n(n+1)*r*1/(2*100*12)

” ” = 600*30*31/2*100*12

Simple Interest .= RS 2335

Now Maturity Value = P*n+S.I.

Maturity Value=600*30+2325

…………………=RS 20325 Ans

(b)

(c)

12500 + 1000

13500

(ii) IGST, CGST and SGST paid by the dealer to the Central and State Government

IGST, is nil due to intra state

CGST paid by the dealer to the Central Government

**Thanks**

information about the solution should be at the top of the page ..

thanks for your suggestion

we will sure solve it in its update version (2021-2022 session)

team icsehelp

yess. And nice thing is that SOLUTION ARE GIVEN AT END…not after each respective question as other Q. paper.

thanks

In Q.paper, There is the absence of questions from chapter TANGENT AND INTERSECTING CHORDS as well as ARITHMETIC PROGRESSION.

*Please look for it.

Also, thanks for making paper from reduced syllabus 🙂 !

pls look for the answer of Q.4(a), it’s answer is 34.64 m not 36.64 m.

“20*1.732”.

ok
