Question
'M’s income is 80% higher than 'N’s. M and N save
25% and 15% of their incomes respectively. If M spends Rs. 1170 more than N, what are M's savings?Solution
ATQ,
Let the income of 'N' be Rs. '100n'
Income of 'M' = 1.8 × 100n = Rs. '180n'
Expenditure of 'M' = 0.75 × 180n = Rs. '135n'
Expenditure of 'N' = 0.85 × 100n = Rs. '85n'
So, 135n – 85n = 1170
Or, 50n = 1170
Or, n = 23.4
Savings of 'M' = 180n – 135n = 45n = 45 × 23.4 = Rs. 1,053
If x, y and z are real numbers such that (x-5)2+(y-7)2+(z-9)2= 0 then (x+y+z) is equal to
? + (35)² = (130)² - (45)² - 2850
If 1/(x+ 1/(y+ 1/z)) = 13/30, then find x+y+z= ?
If x = 99, then the value of x5 - 100x4 + 100x3 - 100x2 + 100x - 1 is
For a =-4 and b = 5, value of a² – b² is:
What will come in the place of question mark (?) in the given expression?
(360 ÷ 24 + 105)% of ? = 48
If there are a total of 1000 students in the school, how many students prefer Mathematics and science?
If (a + b + c) = 9, find (a – 4)3 + (b – 2)3 + ( c – 3)3 - 3(a – 4 ) (b – 2 ) (c – 3)?
