Questions and Answers

A woman invests ¥200 at the beginning of each year for two years in a fixed income bond that pays interest of 8 per cent per annum.

False (B)

The pseudocode algorithm will print 'PERFECT' if the weight is less than 180.0 and the year is any year other than 1990.

False (B)

The final value of the investment after three years in the fixed income bond described in the algorithm depends on the interest being compounded annually.

True (A)

Problem Statement

A clear and concise description of a problem, outlining its scope, impact, and desired outcome. It includes details about the problem's background, relevant factors, and what a satisfactory resolution should achieve.

Algorithm Representation

A method of expressing a step-by-step procedure to solve a problem, allowing the computer to execute steps systematically.

Compound Interest

Calculating interest not only on the principal amount but also on the accumulated interest from previous periods.

Pseudocode

An informal way of describing an algorithm using a combination of natural language and programming-like constructs. It's easier to understand than full code.
