Question
Sneha spends 30% of her monthly income on groceries and 50%
of the remaining on travel. If she saved Rs. 980 after all expenses, then how much money did she spend on travel?Solution
ATQ,
Let monthly income of Sneha be Rs. x
Amount remaining after spending 30% on groceries = 70% of x = 0.7x
Amount spent on travel = 50% of 0.7x = 0.5 × 0.7x = 0.35x
Savings = x - (0.3x + 0.35x) = 0.35x
Now, 0.35x = 980
⇒ x = 980 / 0.35 = 2800
Amount spent on travel = 0.35 × 2800 = Rs. 980

17 × 15 − 96 ÷ 8 + 6² = ?
Evaluate: 144 ÷ 12 × 6 + 35 − 4²
What will come in the place of question mark (?) in the given expression?
21 × 18 + ? – 19 × 15 = 25 × 24
2916 ÷ 54 = ? + 27
√324 + √484 + 63 = ?2
What will come in the place of question mark (?) in the given expression?
{(2/15) + (12/25)} of 375 + 190 = ?% of 375
- What will come in place of the question mark (?) in the following questions?
100−[20+4×5]=? (72 × 52 + 1555 )/(79+60) = 2000 ÷ ?
72 × 2 = ? + 104 – 14
672 ÷ 28 × 24 + 363 – 309 =?
