**Exercise- 12A**

**(**Fundamental Concepts of Algebra Class 6 RS Aggarwal Exe-12A Goyal Brothers ICSE Maths Solutions Ch-12**)**

**Que-1: Write the following in mathematical form using signs and symbols :**

(i) x increased by 23 (ii) y decreased by 15 (iii) x minus thrice y (iv) x taken away from 20 (v) Four times x decreased by five time y (vi) Sum of x and quotient of y by 10 (vii) Product of a and b subtracted from their sum (viii) Quotient of a by 3, multiplied by the sum b and 3.

**Sol: **(i) x+23

(ii) y-15

(iii) x-3y

(iv) 20-x

(v) 4x-5y

(vi) x+(y/10)

(vii) (a+b) -ab

(viii) (a/3)(b+3)

**Que-2: Write the following statements in mathematical form using signs and symbols :**

(i) x exceeds 14 by 5 (ii) Twice x decreased by 9 gives 11 (iii) 45 decreased by y gives 29 (iv) One third of the sum of x and 4 equals y (v) 16 less than the quotient of a by 2 equals 8 (vi) Nine times m is greater than 18 (vii) 7 is greater than twice p (viii) The quotient of a by 6 is less than 1 (ix) Three times x is 12 less than twice y.

**Sol: **(i) x-14 = 5

(ii) 2x-9 = 11

(iii) 45-y = 29

(iv) (1/3)(x+4) = 10

(v) (a/2)-16 = 8

(vi) 9m > 18

(vii) 7 > 2p

(viii) a/6 < 1

(ix) 3x = 2y-12

**Que-3: Write each of the following in exponential form :**

(i) a×a×a×….. taken 10 times (ii) r×r×r×….. taken 6 times (iii) 2×m×m×n×n×n (iv) 3×5×p×p×p×q×q×r

**Sol: **(i) a^10

(ii) r^6

(iii) 2m²n³

(iv) 15p³q²r

**Que-4: Write the following in product form :**

(i) 6x²y³ (ii) 3a²b³c⁴ (iii) 2p³q³r³

**Sol: **(i) 6×x×x×y×y×y

(ii) 3×a×a×b×b×b×c×c×c×c

(iii) 2×p×p×p×q×q×q×r×r×r
