Answer 1

Given:

• The cost of one kg mangoes is ₹60.
• litre juice can be made from 1 kg mangoes,

To Attain:

• how much money does Sonu need to spend on mangoes
• so that he can serve juice to 5 guests in 150 ml glass each?

Solution:

Now let's firstly find the amount of juice which 5 guest need

${ \underline{ \frak{ \dag \: As \: we \: know \: that : }}}$

➭ 1 person is served with 150ml of juice

➭ 5 guests need 5 × 150ml of juice

➭ 5 guests need 750ml of juice

Now,

• To prepare 1000ml of juice you need 1 kg of mangoes

So,

• To prepare 750ml of juice you need 750g of mangoes

Here,

• The cost of 1000g of mangoes is ₹60

Now,

• Let's consider the cost of 750g of mangoes be x

$\qquad{ \underline{ \bigstar{ \textbf{According to the question : }}}}\\ \\ \qquad : \implies \sf \: 1000: 60 : : 750 : x \\ \\ \\ \qquad : \implies \sf 1000 \times x = 750 \times 60 \\ \\ \\ \qquad : \implies \sf 1000x = 45000 \\ \\ \\ \qquad : \implies \sf x = \cancel\frac{45000}{1000} \\ \\ \\ \qquad : \implies \sf { \purple{ \underline{ \boxed{ \pmb{ \frak{x = 45}}}} \bigstar}}$

${\underline{\sf{\therefore \: Hence, \; Sonu\; needs\: to\; spend \; Rs.45\; on \;the \; mangoes}}}$
