ICSE Class 10 Maths Question Paper 2016 With Solution

Question 1:

(a) Using remainder theorem, find the value of k if on dividing 2π‘₯3 + 3π‘₯2 βˆ’ π‘˜π‘₯ + 5 by x – 2, leaves a remainder 7.

(b)

ICSE Class 10 Maths Qs Paper 2016 Solution-1

(c) The mean of following numbers is 68. Find the value of β€˜x’.

45, 52, 60, x, 69, 70, 26, 81 and 94.

Hence estimate the median.

Answer:

(a) 𝑓(π‘₯) = 2π‘₯3 + 3π‘₯2 βˆ’ π‘˜π‘₯ + 5

𝑓(2) = 2 Γ— 23 + 3 Γ— 22 βˆ’ π‘˜ Γ— 2 + 5 M1 (Substitution)

16 + 12 βˆ’ 2π‘˜ + 5 = 7 M1 (equated to 7)

33 βˆ’ 2π‘˜ = 7

∴ 2π‘˜ = 33 βˆ’ 7

2π‘˜ = 26

∴ π‘˜ = 13
