Question

cost of 850 gm meat if 1kg meat is RS 400​

Answer 1

Answer:

WE CAN WRITE 1 KG AS 1000 GRAMS

SO,IF 1000 GRAMS COST RS 400

THEN COST OF 850 GRAMS=?

SO,LET THE COST BE X RUPEES,

1000 G = 400 RUPEES

850 G =X RUPEES

SO,IF THE GRAMS INCREASE,THE COST WILL ALSO INCREASE,SO IT IS A DIRECT VARIATION.

SO X=850 x 400/1000=RUPEES 340

                            OR

WE CAN FIND IT BY FINDING THE RATE FOR 1 GRAM AND THEN MULTIPLY IT BY 850 GRAMS

SO 1000 G = RUPEES 400,THEN 1 GRAM=400/1000=2/5 RUPEES,

NOW 850 GRAMS=850 x 2/5=RUPEES 340,

THANK YOU.
