Mathematics, (www.tiwariacademy.com), (Chapter - 16) (Playing with Numbers), (Class - VIII), Exercise 16.1, Question 1:, Find the values of the letters in the following and give reasons for the steps involved., €. Answer 1: 3 A, On putting A = 1, 2, 3, 4, 5, 6, 7 and so on and we get,, 7+5=12 in which ones place is 2., A=7 B, And putting 2 and carry over 1, we get, B=6, Hence, A=7andB=6, , + 2 5, , Question 2:, Find the values of the letters in the following and give reasons for the steps involved., €. Answer 2: 4A, On putting A = 1, 2, 3, 4, 5, 6, 7 and so on and we get,, 8+5=13 in which ones place is 3. + 9, A=5, And putting 3 and carry over 1, we get C B, B=4andC=1, Hence, A=5,B=4andC=1, , Question 3:, Find the values of the letters in the following and give reasons for the steps involved., €. Answer 3: 1A, On putting A = 1, 2, 3, 4, 5, 6, 7 and so on and we get,, AxA=6x6=36 — inwhich ones place is 6. x A, v3 A=6 ————-—, Hence, A=6 OQ A, , Question 4:, Find the values of the letters in the following and give reasons for the steps involved., €. Answer 4: A B, Here, we observe that B=5 so that 7 +5 =12., Putting 2 at ones place and carry over 1 and A= 2, ( 3 7, we get2+3+1=6 ~, Hence, A=2andB=5, , 6 A, , Question 5:, Find the values of the letters in the following and give reasons for the steps involved., €. Answer 5: A B, Here on putting B = 0, we get0 x 3 = 0., And A=5,then5x3=15 x 3, => <A=S5andC=1 za =a, Hence, A=5,B=OandC=1 CA B, , www.tiwariacademy.com, A Free web support in Education, , 1
