In a
cricket match Sachin and Viru scored century (more than 100 runs) and Yuvi and
Gauti scored half century. Gauti scored 76 runs and Yuvi scored 12 runs less
than Gauti. Viru scored 102 runs. The sum of the scores of all the four players
is 442. How many runs did Sachin score?
Solution:
Given
all the players scored 442 runs.
Given Gauti
scored 76 runs.
Given
Yuvi scored 12 runs less than Gauti. Therefore score of Yuvi is
76-12=64.
Given Score
of Viru is 102.
Therefore
score of Sachin is 442-(76+64+102) = 200.
In a school
there are 800 students. Out of whom 12 % are girls. Each boy’s monthly fee is ` 200/- and each girl’s monthly fee is
25% less than a boy. What is the total monthly fee of girls and boys together?
Solution:
Given
the total number of students are 800.
Number of
girls are 12% of 800
= 800
x 12 =96
100
Therefore
number of boys = 800-96 = 704
Monthly
fee of a boy is `220/-. Therefore monthly fee of girl =
220x75 = 165/-.
100
Therefore
total monthly fee = 704 x 220 + 96 x 165
=
154880+ 15840
=170720
