Answer 2

Answer:

Step-by-step explanation:

lets focus on "they share the butter naans and roties equally"

then the formula for distribution and the amount that they get will be :-

For Amar,

$\frac{N}{3} + 4R = 10$

For Bharat,

$\frac{13N}{3} + 2R = 30$

by solving these 2 we will get the cost of the naan and roti as 6 and 2 respectively.

now the cost of both the products and calories in them are in proportion so by that we can get the calories of roti by the unitary method

$\left[\begin{array}{ccc} &naan&roti\\cost&6&2\\cal.&150&?\end{array}\right]$

Ans. is 50.
