A mathematics textbook has 420 pages. 35% of the pages are on number, 30%

are on algebra and the remainder are on shape. How many pages are there on shape?

Answer 1

35% is on Shape which is 147 pages

Explanation:

Total pages 420 = 100%

30% on Algebra + 35% on Numbers = 65%

100% - 65% = 35% on Shape

35% of 420 pages =

35/100 * 420 = 147 pages on Shape

Answer 2

35%=147
30%=126
147+126=273
420-273=147
Answer is 147
