Answer 1

$\bf{ \underline{★ᴬᴺˢᵂᴱᴿ★}}$

• The cost of 35 bags of wheat is Rs.4812.5

$\bf{ \underline{Given :}}$

• 25 bags of wheat each weighing 40 kg cost Rs 2750.

$\bf{ \underline{To \: find :}}$

• The cost of 35 bags of wheat, if each bag weighs 50 kg ??

$\bf{ \underline{solution :}}$

☯ Let the cost of each bag be 'x'

$\bf{ \underline{➥According \: to \: the \: question:}}$

$\longrightarrow{25x = 2750}$

$\longrightarrow{x = \frac{2750}{25}}$

$\longrightarrow{x = 110}$

${ \bold{Cost \: of \:  40 kg's \: wheat =110}}$

$\bf {Cost \: of  \: 1 kg \: wheat = \frac{110}{40}}$

$= \frac{11}{4}$

$\bf{Now, we \: have \: to \: find \: the \: cost \: of  \: 50 kg</p><p></p><p>}$

$\longrightarrow{∴cost = 50 \times \frac{11}{4}}$

$\longrightarrow{ = \frac{550}{4}}$

$\longrightarrow{ = Rs.137.5}$

$\bf{Now, \: the \: cost \: of  \: 35 \:  bags}</p><p></p><p></p><p>$

$\longrightarrow{35 \times 137.5}$

$\longrightarrow{\boxed{ \blue{Rs.4812.5}}}★$

∴ Thus, The cost of 35 bags of wheat is Rs.4812.5

Answer 2

let the cost of each bag be x

According to the question,

2x = 2750

x = 2750/2

x = 110

Cost of 40 bags wheat = 110

Cost of 1kg wheat = 110/40

= 11/4

Now, we have to find the cost of 50kg

Therefore, cost = 50 × 11/4

= 550/4

= Rs. 137.5

Now, cost of 35 bags

= 35×Rs.137.5

= Rs. 4812.50
