Question
A person gives 20% of his salary to his wife and 25% of
the remaining to his children. Now he is left with Rs. 27000. What is his total salary?Solution
Let the total salary be x x × (100 – 20)% × (100 – 25)% = 27,000 x ×  80/100 ×  75/100 = 27,000 x = (27000 ×100 ×100)/(80 ×  75) = Rs.45,000
25% of 300 + √(?) = 35% of 600 - 15% of 300
What will come in the place of question mark (?) in the given expression?
128 + 16 X 6 - ? = 88 + 4 X 26Â
15848 ÷ 4 – 793 × 6 + 3628 = 3 × ?
12 × 19 + 13 × 15 + 152 = ?% of 500
- Find the value of the expression:
15 + 10 – 6 × [20 + 8 – 2 × (50 – 35)] 30% of 40% of 120% of 3500 = ? × 63
7/3 of 4/5 of 15/56 of ? = 83
140% of 75 + 152 - 160 = ?
Evaluate
64 ÷ 4 of 5 of [10 ÷ 5 of (9 ÷ 3 + 2)] + (9 ÷ 3 + 1)
