(a) In an examination, 29,456 candidates passed while 57,281 candidates failed. How many candidates appeared for the examination?
Number of candidates passed = 29,456
Number of candidates failed = 57,281
Total candidates appeared = 86,737
Thus, 86,737 candidates appeared for the examination.
(b) In a school library, there are 11,250 Science books, 21,312 Maths books and 20,143 Hindi books. Find the total number of books in the library.
Number of Science books = 11,250
Number of Maths books = 21,312
Number of Hindi books = 20,143
Total number of books = 52,705
Thus, total number of books in the library is 52,705.
(c) In a school, there are 1,752 students in primary classes, 1,825 in middle classes and 1,790 in senior classes. Find the total strength of school.
No. of students in primary classes = 1,752
No. of students in middle classes = 1,825
No. of students in senior classes = 1,790
Total strength = 5,367
Thus, total strength of school is 5,367.
(d) The cost of a black and white T.V. set is ₹ 3,690. The cost of a colour T.V. set is ₹ 12,810 more than the cost of black and white T.V. set. Find the total cost of both the T.V. sets.
Cost of black and white T.V. set = ₹ 3,690
Cost of colour T.V. is ₹ 12,810 more than black and white T.V.
So, cost of colour T.V. = ₹ 23,690 + ₹ 12,810
= ₹ 16,500
Total cost of both T.V. sets
= ₹ (16,500 + 3,690)
= ₹ 20,190
Thus, cost of both the T.V. sets are ₹ 20,190.
