Satish wean to a hotal with his famili . They consume 20 idly , 9 dosa and 5 somasa and paid Rs. 208 . Mahesh went to the same hotal with his famili . they consume 16 idlies , 11 dosas and 9 somasa and paid Rs 232 .If one idly cost the same as somasa . Find the cost of one dosa .

@​ Priyanka- Good attept but after solving you will get  x = 4.

i think it is Rs 12.

let the cost of one idly and samosa be x

let the cost of dosa be y

since cost of one idly = cost of one samosa

therefore in the first eq. 20x +9 y + 5 x = 208 or 25x +9y = 208

second eq .16x+ 11y+9x = 232 or 25x + 11y = 232

therefore on solving it we get x = 12

thumbs up plz
