Problema Solution
in a science test, john scored thrice as many marks as Ahmad. if Raju had 10 more marks, he would have scored the same marks as john. the total marks the boys scored were 214. how many marks did Raju and Ahmad scored altogether?
Answer provided by our tutors
let 'a' represent Ahmad's score, then '3a' represents john's score and '3a-10' represents Raju's score:
214 = a + 3a + 3a-10
solving for 'a' we have a=32
32 + 3*32-10 = 118
together, Ahmad and Raju scored 118 marks
