Q:

Negative plus a positive equals

A) negative B) positive
C) zero D) Can't be determined
 
Answer & Explanation Answer: D) Can't be determined

Explanation:

We know that a negative value plus a positive value always count backward and the sign depends on the bigger value sign.

When you are adding a negative number to a positive number, then the value counts backward and takes the sign of the biggest number.

 

For example::

Adding -5 and +2

-5 + 2 = -3 (big number is 5 and its sign is '-')

 

Adding -3 and  +5

+5 + (-3) = 5 - 3 = +2(big number is 5 and it has sign '+').

Q:

A kiddy bank of a child contains all Rs. 1, 50 paise and 25 paise coins. What is the total amount in the bank ?
(1) Total number of coins are 20
(2) The number of 50 paise and 25 paise coins are in the ratio of 7:3.

A) only 1 is needed B) only 1 is needed
C) Both and 2 are needed D) None
 
Answer & Explanation Answer: C) Both and 2 are needed

Explanation:

Given that 50 paise and 25 paise coins are in the ratio of 7:3, they can be either 7 & 3 or 14 & 6.
As total 20 coins also includes Rs. 1 coins, so 50 paise & 25 paise coins are 7 & 3 respectively & Rs. 1 coins are 10.
Total amount = (100x10) + (50x7) + (25x3)=1425 paise or Rs.14.25.
