Question
A scored 32% marks and failed by 70 marks whereas B
scored 64% marks, which was 90 more than the passing marks of the examination. Find the total marks of the examination.Solution
Let the total available marks in the examination be 100x. Marks scored by A = 32% of 100x= 32x Marks scored by B = 64% of 100x= 64x According to question, => 32x + 70 = 64x – 90 => 32x = 160 => x = 5 Total marks of the examination = 100x = 500
22% of 400 + √ ? = 34% of 800 - 25% of 400
216% of 350 + 273 = ?2 × 21
Simplify the given expression:
[(2.3)3 + (15.9) ³ + (3.7) ³ – 3 × 2.3 × 15.9 x 3.7)] / [(2.3) ² + (15.9) ² + (3.7) ² – 2.3 ...
25639 – 5252 – 3232 = ?
What will come in the place of question mark (?) in the given expression?
The income of a person is Rs.15000 and his expenditure is Rs.12000. In the next year his income and expenditure is increased by 8% and 13% respectively....
[{70 + (40 - 22) ÷ 3} ÷ 4] = ?
12% of 10% of 15% of 5000 + (12 x 15) = ?
Find the value of ?
{[(864 ÷ 18) ÷ 8] ÷ 3} + 11² – 2³ = ?
