Q73 of 100 Page 312

Observe the following nutritional chart carefully:


Write an algebraic expression for the amount of carbohydrates in ‘g’ for


(a) y units of potatoes and 2 units of rajma (b) 2x units tomatoes and y units apples.

(a) 1unit potato is 22gm carbohydrates

y unit = 22y gm carbohydrates


2 units rajma gives 60×2 gm carbohydrates


22y + 120 is the expression for carbohydrates.


(b) 1 unit tomatoes have 4gm carbohydrates


2x unit will have 2x×4 unit carbohydrates i.e., 8x gm carbohydrates.


Similarly, y unit apples will have 14y gm carbohydrates.


⇒ 8x + 14y is the required expression.

Each symbol given below represents an algebraic expression:

= 2x2 + 3y, = 5x2 + 3x, = 8y2 – 3x2 + 2x + 3y


The symbols are then represented in the expression:
