Question

The mass of a durian is three times the mass of two apples. The mass of a big watermelon is twice the mass of the durian. The total mass of the fruits is 2.5 kg. What is the mass of one apple?

Answer 1

Answer:

Let the mass of two apples be x

then, mass of durian be 3x

mass of watermelon be (2 × 3x) = 6x

Total mass of fruits = 2.5 kg ( Given )

then,

=> x + 3x + 6x = 2.5 kg

=> 10x = 2.5 kg or 2500 gram (g)

=> x = 2500/10

=> x = 250 g

The mass of two apples = 250 g

then, mass of one apple = 250 ÷ 2

= 125 g or 0.125 kg

facts use in question is 1 kg = 1000 g

Answer 2

Answer:

The mass of an apple is $125kg$.

Step-by-step explanation:

It is given that the mass of a durian is three times the mass of two apples.

Let mass of apple be $m$.

Mass of durian is $3(2m)=6m$.

The mass of a big watermelon is twice the mass of the durian.

So the mass of big watermelon is $2(6m)=12m$

The total mass of the fruits is $2.5 kg$.

According to question,

$2m+6m+12m=2.5$

$20m=2.5$

$m=2.5/20$

$m=0.125$

Mass of an apple is $125gm$.
