Question
A man receives ₹3840 per month as salary. He saves 15%
of his salary every month. His expenditure (in ₹) per month is:Solution
Given: Salary = ₹3840 Savings = 15% of salary Calculate savings Savings = (15/100) × 3840 = ₹576 Calculate expenditure Expenditure = 3840 − 576 = ₹3264
5 + 2 × 3 ÷ (3 × 2) ÷ 4
What will come in the place of question mark (?) in the given expression?
(√1089 + √484) X 5 + ? = 725
Simplify the following expression:

44% of 1250 + 46 × 34 = 40% of ? + 1154
The value of 3 × 7 + 5 – 6 ÷ 3 – 9 + 45 ÷ 5 × 4 – 45 is:
35% of 500 × 22% of ? = 847
((9.77)0- 〖(0.1)〗(-1))/(〖(6/24 )〗(-1) ×(3/2)3+ 〖((-2)/6)〗(-1) ) = ?
...- What will come in place of (?) in the given expression.
(14)² – (12)² = ? 20 + 160/? × 20 = 420
2048 × 1824 ÷ 76 = (? - 212) × 64
