SECTION-II:

Find the values for the following problem:
f(X)= 2X-1 + f(X-1) if X is not equal to zeroandiff(X=0)=0

9. Value of f(5)

a)15
b)24
c)22
d)None

10. Value of f(f(2))

11. Value of f(16)- f(15)

12. Value of f(16)+f(15)-480

13. If f(f(X))=81 then the value of X=?

14. If f(X)=4f(X-1) then the value of X=?

15.If f(X)= f(X-1)+f(X-2) for X>1 then X= ?

16. If f(X)-f(X-1)=f(X-8) for X>5 then X=

SECTION 3

A 'TARGET' is a number and 'BRICK' has five numbers as clue.
Use only four numbers (only once each number) from 'BRICK' using arithmetic opertions,

+,-,*,/,() and attain the 'TARGET'
1. TARGET = 114 BRICK =
2. TARGET = 19 BRICK = 8,11,5,5,2
3. TARGET = 87 BRICK =
4. TARGET = 146 BRICK =
5. TARGET= 127 BRICK =

Ans:
for 2 questions
19 = (8+11-5+5)
so ans = (8,11,5,5)

SECTION 4

All the questions are of multiple choice type. You have to answer the questions All the questions are of multiple choice type. You have to answer the questions based on the preceding paragraph. All the questions have the same answer choice. The choices are as given below:
(a) True.
(b) False.
(c) Cannot Say.

Consider the following paragraph:

Statistics show that millions of vehicles have been carried by shuttle over the past 30 years through Alpine tunnels without one ever catching fire. In the Alpine tunnels, drivers and passengers sit in their vehicles on the shuttle trains. Only one vehicle has ever caught fire on the busy French motorail equivalent system. This sort of accident is not possible in a closed shuttle. Assertion that a vehicle fire will lead to catastrophe have no basis. Since the resources exist to detect, control and extinguish a fire, and to remove any persons present safely to an adjoining wagon, leaving any surviving fire facing rapid extinction within a wagon built to contain fire for 30 minutes, catastrophe seems very unlikely.

# " It is theoretically possible for a vehicle to catch fire even in a closed wagon".

# " The French motorail system is inferior to the shuttle train system."

# "No accident can occur in the closed tunnels".

# "Fire is allowed to live for 30 min".

# "All the cars that travel in the tunnels will be carried by rail shutters".
