Question
A sum of Rs. 46,000 was divided between 'A' and 'B' such
that the amount received by 'B' was 30% more than that by 'A'. If 'A' and 'B' spent 10% and 25% of the respective amounts received by them, then find the sum of amounts spent by 'A' and 'B' together.Solution
Let the amount received by βAβ = Rs. β10xβ Then amount received by βBβ = 10x Γ 1.3 = Rs. β13xβ we have, 10x + 13x = 46000 So, x = 46000 Γ· 23 = 2000 So, amount received by βAβ = 10 Γ 2000 = Rs. 20,000
Amount received by βBβ = 13 Γ 2000 = Rs. 26,000 Amount spent by βAβ = 20000 Γ 0.1 = Rs. 2,000
Amount spent by βBβ = 26000 Γ 0.25 = Rs. 6,500 So, required sum = 2000 + 6500 = Rs. 8,500
Simplify the following expressions and choose the correct option.
18 * 15 - {3/5 of 250 + 72}
Simplify the given expression.

If 1560 Γ· 30 + 2025 Γ· 45 - z + 33 Γ 7 = 1848 Γ· 24 Γ 234 Γ· 39, then the value of z is:
2350 – 4830 + 9570 + 3350 – 1720 = ?
What should come in place of (?) question mark in the given expression.
[60% of 350 + (2/7 of 210)] Γ· 5 = ?
15% of 1800 + 22 = ?Β
- Calculate the value of this expression:
(180 - 90 Γ· 6 of 2) Γ· 5 + 3 of 16 Γ· 4 - 12 of 4 Γ· 8 (7/5) × (3/4) × (5/9) × (6/7) × 3112 = ?
Determine the value of 'p' in following expression:
720 Γ· 9 + 640 Γ· 16 - p = β121 X 5 + 6Β²- 7
