Question : 1
The sum of all the 3-digit numbers, each of which on division by 5 leaves remainder 3, is
a) 6995
b) 180
c) 1550
d) 99090
Answer »Answer: (d)
According to the question,
First number = a = 103; Last number = l = 998
If the number of such numbers be n, then,
998 = 103 + (n – 1) × 5
(n – 1) × 5= 998 – 103 = 895
n – 1 = $895/5$ = 179
n = 180
S = $n/2(a+l)$
=$180/2$(103 +998)
= 90 × 1101 = 99090
Question : 2
The sum of first 50 odd natural numbers is
a) 5200
b) 1000
c) 1250
d) 2500
Answer »Answer: (d)
S = 1 + 3 + 5 + ..... to 50 terms
Here, a = 1; d = 3 – 1 = 2; n = 50
S = $n/2[2a + (n - 1)d]$
= $50/2[2×1+ (50 - 1) ×2]$
= 25 (2 + 98) = 25 × 100 = 2500
Question : 3
If the sum of five consecutive integers is S, then the largest of those integers in terms of S is
a) ${S + 5}/4$
b) ${S -10}/5$
c) ${S + 4}/4$
d) ${S +10}/5$
Answer »Answer: (d)
Sum of five consecutive integers = S
Third integer = $S/5$
Largest integer = $S/5$ + 2 = ${S+10}/5$
Question : 4
The sum of all natural numbers between 100 and 200, which are multiples of 3 is :
a) 4980
b) 5000
c) 4950
d) 4900
Answer »Answer: (c)
Numbers divisible by 3 and lying between 100 and 200 are : 102, 105,..... 198
Let number of terms = n
198 = 102 + (n–1) 3
n–1 = ${198 - 102}/3$ = 32
n = 33
S = $n/2$(a+l) =$33/2$(102+ 198) = 4950
