(c) Rs. 23600                                        

(d) Rs. 12600

(e) None of these

His total income in a month = Rs. 36000

His total expenditure in a month = Rs. 1500 + Rs.  3600 + Rs.  7500 = Rs. 12600

Therefore, his saving in a month = Rs. 36000 - Rs. 12600 = Rs. 23400  

 

 

A book contains 1256 pages. 256 pages are blue, 186 pages are green and rest of the pages are white. Find the difference between the numbers of white pages and blue pages:

(a) 814                                                 

(b) 1000

(c) 628                                                  

(d) 558

(e) None of these

 

Answer: (d)

Total number of pages in the book = 1256

Total number of blue and green pages = 256 + 186 = 442

Therefore, total number of white pages = 1256 - 442 = 814

Difference between the numbers of white and blue pages = 814 - 256

= 558
