In an election between two candidates 10% voters doesn’t cast their votes and 85 votes were de
Explanation:
Lets take total votes =100% 10%doesn’t cast their votes So, (100-90) = 90% cast their votes. total valid votes = 90% -85 one candidate get 50% of votes of voters list. So, other candidate get = (90% - 85 )-50%= 40% - 85 so ,50 % - (40% - 85) = 165 50% - 40% + 85 = 165 10% = 80 100 % = 800 So total voters is 800

A Trader Who Marks His Good Upto 50% And Offered Discount Of 20% . What % Profit The Trade Makes After Offering The Payment?
Explanation:
Sol. Let cp = 100, MRP = 150
\( sp = 150 \times {80 \over 100} \)
\( = Rs. 120 \)
Hence, Profit = 20%
[short trick:]
By successive formula
\( x+y+{xy \over 100} \)
\( 50-20+{50 \times (-20) \over 100} \)
30 – 10 = 20%

What number has 5 to 1 ratio to the number 10?
Explanation:
Given, ratio is 5 : 1 that means antecedent is 5 times greater than the consequent.
Given consequent = 10, so the number is 10 × 5 = 50 answer.

There are 120 students in a picnic tour, if ratio of girls and boys is 5 : 7 then how many boys are in this tour?
Explanation:
Given ratio of girls : boys = 5 : 7 = 5/7
multiplying the antecedent and consequent by the same number, let by x,
girls = 5x, and boys = 7x
total = 120;
as par given 5x + 7x = 120
=> x = 120/12 = 10
hence, girls = 5 × 10 = 50
and Boys = 7 × 10 = 70 answer

Explanation:
in a ratio the first term is called antecedent and the second term is called consequent. in 3 : 5, 3 is antecedent and 5 is consequent, means and extremes are terms used in case of proportion
i.e. 1 : 2 :: 2 : 4, here 1 and 4 are extremes and 2 and 2 are means.
