Answer:
21. Both are true
Usually, the square of the number with n digits is either of 2n or 2n-1 digits.
22. Pythagorean triplet is when sum of the squares of the lowest two digits is equal to the square of the third digit.
In the options given, Only in option d):
(8)^2 + (15)^2 = (17)^2
=> 64 + 225 = 289
=> 289 = 289
Answer:- (d)
23. In the AP:
a = 51
d = 1
l = 99
l = a + (n-1)d
=> 99 = 51 + (n-1)1
=> 48 = n - 1
=> n = 49
sum:
s = n/2(a + l)
=> s = 49/2(51+99)
=> s = 49/2(150)
=> s = 49×75
=> s = 3675
Answer:- (b) 3675
24. According to the property told in question 21, answer should be:
(c) 1005
25. Pythagorean triplet is: 2m, m^2 - 1, m^2 + 1, where largest number is m^2 + 1:
=> m^2 + 1 = 101
=> m = 10
Numbers:- 2m = 20, 99, 101
(a) is correct.
