60और 6000 के बीच ऐसी 56 संख्याएं हैं 15 से विभाजित तो शेषफल 7 & 21 से विभाजित किया जाता है तो शेषफल 10
Step-by-step explanation:
15a + 7 = 21b + 10
60 < 15a + 7 < 6000
=> 53 < 15a < 5793
=> 3 < a < 400
60 < 21b + 10 < 6000
=> 2 < b < 286
=> 15a = 21b + 3
=> 5a = 7b + 1
b = 7 a = 10 157
b = 12 a = 17 262
b = 17 a = 24 367
b = 282 a = 395 5932
157 , 262 , ........................................... 5932
a = 157
d = 105
5932 = 157 + (n-1)(105
=> n - 1 = 55
=> n = 56
60और 6000 के बीच ऐसी 56 संख्याएं हैं
or we could find LCM of 15 & 21 = 105 to find difference between numbers
