প্রথম সংখ্যার পর থেকে পরপর দুইটি সংখ্যার যোগফল পরের সংখ্যাটি ।
১ম পদ = 1
২য় পদ = 1
৩য় পদ = 1 + 1 = 2
৪র্থ পদ = 2 + 3 = 5
৫ম পদ = 3 + 5 = 8
৬ষ্ঠ পদ = 5 + 8 = 13
৭ম পদ =13 + 8 = 21

Question: Father is aged three times more than his son Ronit. After 8 years, he would be two and a half times of Ronit's age. After further 8 years, how many times would he be of Ronit's age?

Solution:
Let Ronit's present age be x years.
Then, father's present age =(x + 3x) years
= 4x years

Now
4x + 8 = (5/2)(x + 8)
8x + 16 = 5x + 40
8x - 5x = 40 - 16
3x = 24
x = 8

Further 8 years will means 16 years from the current age.
After 16 years from present, Ronit's age be (8 + 16) = 24 years
After 16 years from present, father's age be (8 × 4 + 16) = 48 years

After 16 years from present the ratio of their ages will be 
His father's age/ Ronit's age = 48/24 
His father's age/ Ronit's age =2
His father's age = 2 × Ronit age

Question: If one-third of one-fourth of a number is 15, then three-tenth of that number is-

Solution:
Let, the number is 'x'

Now
(1/3) × (1/4) × x = 15
⇒ x/12 = 15
⇒ x = 12 × 15
x = 180

three-tenths of that number will be = (3x/10)
= (3 × 180/10) 
= 18 × 3
= 54.

Question: How many seconds will a 500 metre long train take to cross a man walking with a speed fo 3 km/ hr in the direction of the moving train if the speed of the train is 63 km/hr?

Solution:
Speed of the train =(63 - 3)km/hr
= 60km/hr
= (60 × 1000)/3600 m/sec
= 50/3

Time taken to pass the man = 500/(50/3) sec
= 500 × (3/50) sec
= 30 sec

Question: A man walks a at a rate of 10 mph. After every ten miles, he rests for 6 minutes. How much time does he take to walk 50 miles?

Solution:
The man needs time = 50/10 = 5 hours
= (5 × 60)
= 300 minutes

He will also rest 4 times after 10, 20, 30 and 40 miles
Total resting time = 4 × 6 = 24 minutes.

Total time = 300 + 24 = 324 minutes
