Number with more digits will be larger. - If number of digits are same, compare the most signif icant (lef t-most) digit. Number with higher digit at this place will be larger. - If lef t-most digits are same, compare next digit (towards right), until we f ind a case where digits dif f er Let's f irst compare number of digits of 61309448 and 17598749, Number of digits in 61309448 = 8 Number of digits in 17598749 = 8 Let's compare 1 st digit f rom lef t. 1 st digit f rom lef t in 61309448 = 6 1 st digit f rom lef t in 17598749 = 1 Since 6 > 1, 61309448 > 17598749
(5) b. 286692 ID : in-4-large-numbers [4] Number of books published in the year 1992 = 55511 Number of books published in the year 1993 = 54983 Number of books published in the year 1994 = 79793 Number of books published in the year 1995 = 96405 Step 5 Number of books published in the year 1992 Number of books published in all f our years = + Number of books published in the year 1993 + Number of books published in the year 1994 + Number of books published in the year 1995 Step 6 Let's do the addition: 5 5 5 1 1 + 5 4 9 8 3 + 7 9 7 9 3 + 9 6 4 0 5 2 8 6 6 9 2 Step 7 Theref ore, the total number of books published by the publisher in f our years was 286692. (6) a. 1099998 T he largest 5- digit number is: 99999 T he greatest 6- digit number is: 999999 T he sum is: 1099998 Hence, the sum of the largest 5-digit number and the greatest 6-digit number is 1099998. (7) d. 30000000 + 7000000 + 600000 + 20000 + 2000 + 900 + 20 + 9
(8) d. 400 ID : in-4-large-numbers [5] We know that a scale is balanced, when weight on both sides are equal. Lef t span of balance has 4.8kg salt, while right span has 4.4kg salt. Theref ore we need to add dif f erence between two weights to right side span in order to balance the scale Theref ore amount of salt to be added right span, = 4.8 kg - 4.4 kg = 0.4 kg = 0.4 1000 grams = 400 grams (9) (10) (11) > > eighty- nine lakh eleven thousand two hundred ninety- one (12) (13) 9629000 90001 The smallest 6 digit number = 100000 The largest 4 digit number = 9999 Dif f erence between them = The smallest 6 digit number - The largest 4 digit number = 100000-9999 = 90001 Theref ore, the dif f erence between the smallest 6 digit number and the largest 4 digit number is 90001.
(14) 9771919 ID : in-4-large-numbers [6] Here we are looking f or a number which is 10079 less than 9781998. We can f ind such number by subtracting 10079 f rom 9781998. Let us now subtract the numbers 10079 and 9781998 as below: 9781998-10079 9771919 Thus, 10079 less than 9781998 is 9771919. (15) A) 4343435 The successor of 4343434 is 4343434 + 1 = 4343435. B) 2411194 The successor of 2411193 is 2411193 + 1 = 2411194. C) 1700000 The successor of 1699999 is 1699999 + 1 = 1700000. D) 89500 The successor of 89499 is 89499 + 1 = 89500. E) 3287037 The successor of 3287036 is 3287036 + 1 = 3287037. F) 4702890 The successor of 4702889 is 4702889 + 1 = 4702890.
