In 2020, A would be 8 years older than B who would be eleven times as old as C. Also, the total of the ages of A, B and C in 2019 would be 143 years. What is the average of A and B ages in 2024 ?
OPtion
1) 70 years
2) 71 years
3) 72 years
4) 77 years
5) 76 years
6) 75 years
7) 74 years
8) 78 years
9) 73 years
10)None of these
Solution
Total ages of A+B+C in 2019 = 143
Total ages of A+B+C in 2020 = 143 + 3 = 146 years
In 2020
Letâ€™s assume Age of B be B years
Age of A = B+8
Age of C = B/11
Total age = B + 8 + B + B/11 = 146
Solving 23B/11 = 136
B = 66
A = B+8 = 74
C = 66/11 = 6
In 2024 - i.e. 4 years later
Age of A = 74+4 = 78
Age of B = 66+4 = 70
YEH 25-5-8 DIL 4-9-12 MANGE 13-1-14-7-5 MORE 13-15-18-5
Value of Smallest positioned alphabet in YEH = 5
Value of Smallest positioned alphabet in DIL = 4
Value of Smallest positioned alphabet in MANGE = 1
Value of Smallest positioned alphabet in MORE = 5
Product of all Values of Smallest positioned alphabets = 5*4*1*5 = 100
Similarly the code for TASTE THE THUNDER:
TASTE 20-1-19-20-5
THE 20-8-5
THUNDER 20-8-21-14-4-5-18
Value of Smallest positioned alphabet in TASTE = 1
Value of Smallest positioned alphabet in THE = 5
Value of Smallest positioned alphabet in THUNDER = 4
Product of all Values of Smallest positioned alphabets = 5*4*1 = 20
Lets arrange the letters of UBIQUITOUS alphabetically = BIIOQSTUUU
Words starting with B = 9!/(2!*3!) = 30240
Words starting with I = 9!/(3!) = 60480
Words starting with O = 9!/(2!*3!) = 30240
Words starting with Q = 9!/(2!*3!) = 30240
Words starting with S = 9!/(2!*3!) = 30240
Words starting with T = 9!/(2!*3!) = 30240
Words starting with UBII = 6!/(2!) = 360
Words starting with UBIO = 6!/(2!) = 360
Words starting with UBIQI = 5!/(2!) = 60
Words starting with UBIQO = 5!/(2!) = 60
Words starting with UBIQS = 5!/(2!) = 60
Words starting with UBIQT = 5!/(2!) = 60
Words starting with UBIQUIO = 3! = 6
Words starting with UBIQUIS = 3! = 6
Words starting with UBIQUITOSU = 1
and next word is UBIQUITOUS = 1
Preeti invests a part of Rs. 35,000 in 10% stock at Rs. 110 and the remainder in 15% stock at Rs. 115. If her total dividend per annum is Rs. 3750, how much does she invest in 10% stock at Rs. 110?
