5. Find the ratio of the price of coffee to that of tea, if coffee costs 48 per 100 gm and tea costs ? 280 per kg.

COFEE COSTS - RS 48 PER 100 GRAM

COFEE COSTS - RS 48 PER 100 GRAMTEA COSTS - RS 280 PER KG

COFEE COSTS - RS 48 PER 100 GRAMTEA COSTS - RS 280 PER KGRATIO OF THE PRICE COFFEE TO THAT OF TEA - RS 48 PER 100 GRAM MEANS THAT 480 PER KG = 480/ 280 - 12:7

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
