Question

(a) Write the following equations in word form. [4 MARKS]

i) $7x+4=46$

ii) $\frac{5x+4}{6}=13$

(b) Raju’s father’s age is 5 years more than three times Raju’s age. Find Raju’s age, if his father is 44 years old.

Answer 1

(a) Correct interpretation of equation: 1 Mark each
(b) Framing of equation: 1 Mark
Solution: 1 Mark

(a) i) When a number is multiplied with 7 and their product is added with 4, we get 46 as the final result.

ii) When a number is multiplied with 5, their product added with 4 and their final sum is divided by 6, the result which we get is 13.

(b) Let Raju's age be x.
Raju's father's age = $3x+5=44$

$\Rightarrow 3x+5=44$

$\Rightarrow 3x=44-5=39$

$\Rightarrow x=\frac{39}{3}$

$\Rightarrow x=13years$
