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
What value should come in place of (?) in the given expression.
450 ÷ 9 + 75% of 160 − 64 ÷ 4 = ?
2/5 of 3/4 of 7/9 of 14400 = ?
7/3 of 4/5 of 15/56 of ? = 83
[564 + 32 of 18 × 9 ÷ 12 + 162 ] ÷ 4 = ?
What should come in place of (?) question mark in the given expression.
(25% of 320) + (3/8 of 400) − 30 = ?
45% of 360 - 160 + ? = √324
187 ÷ 5 ÷ 0.4 = ? – 24 × 2.4
Find the simplified value of the following expression:
[{12 + (13 × 4 ÷ 2 ÷ 2) × 5 – 8} + 13 of 8]
18 × 15 + 86 – 58 =? + 38
√(24²+285-8²-172) = ?²
