In a class of 45 students the ratio of the number of boys and girls is 4 :5 The average score of boys in mathematics is 78 .If the average score of all the students in the class in mathematics is 76 , then what is the average score of girls in mathematics ?

In a class of 45 students, the ratio of the number of boys and girls is 4:5. The average score of boys in mathematics is 78. If the average score of all the students in the class in mathematics is 76, then what is the average score of girls in mathematics?

In a class test,the sum of the marks obtained by P in Mathematics and science is 28. Had he got 3 marks more in Mathematics and 4 marks less in Science.The product of his marks, would have been 180. Find his marks in the two subjects.

In a class test, the sum of the marks obtained by P in mathematics and science is 28. Had he got 3 more marks in mathematics and marks less in science, the product of marks obtained in the two subjects would have been 180. Find the marks obtained by him in the two subjects separately.

Express each of the following in the language of ratios: In a class, the number of girls in the merit list of the board examination is two times that of boys. The number of students passing mathematics test is 2/3 of the number that appeared.

The probability that a student passes in mathematics is 4/9 and that he passes in physics is 2/5. Assuming that passing in mathematics and physics are independent of each other, what is the probability that he passes in mathematics but fails in physics ?
