(a) Write the statement of the following equations. [4 MARKS]
i) 7x+4=46
ii) 5x+46=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.
(a) Correct statement of equation: 1 Mark each
(b) Framing of equation: 1 Mark
Solution: 1 Mark
(a) i) When a number is multiplied with 7 and 4 is added to their product, we get 46 as the final result.
ii) When a number is multiplied with 5, 4 is added to their product 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
⇒3x+5=44
⇒3x=44−5=39
⇒x=393
⇒x=13 years
Raju's age is 13 years.
