You're moving the decimal 7 places to the left so the answer is 9.647 x 10^7
If you calculate you will find x = 2
31x + 3 = 65
67x + 1 = 135
To make a cake :-
Quantity of flour needed = 500 g
Quantity of butter needed = 450 g
Quantity of sugar needed = 470 g
Quantity of mixed fruit needed = 1.8 kg = 1000 g + 800 g
Quantity of eggs needed = 70 × 4 = 280 g
It's weight after adding all the ingredients =
=500 + 450 + 470 + 1000 + 800 + 280
= 3500 g
Mass that got lost while baking the cake :
<h3>= 12 % of 3500 </h3>





Final mass = Initial mass - mass that got lost


∴ The final mass of the cake is 3080 g .
1 Lb is equal to 0.453592 Kg.
Therefore 8.5 Kg is equal to 18.7 Lbs. If you round 18.7 you get 19 Lb.
