Question
Soham and Tanmay started a firm. Soham invested Rs. 12,000
for the whole year, and Tanmay withdrew after 8 months. If the profit at year-end was divided in the ratio 6:5, what amount did Tanmay invest?Solution
ATQ,
Let Tanmay’s investment = y
(12000 × 12) : (y × 8) = 6 : 5
→ 144000 / (8y) = 6 / 5
→ 18000 / y = 6 / 5
→ y = 18000 × (5 / 6)
→ y = Rs. 15,000
(630 ÷ 18 + 24 of 25) ÷ 5 = ?
(18 × 9 ÷ 6) × 3 = ?
√225 + 27 × 10 + ? = 320
Simplify the expression:
(9x² - 25) / (3x + 5)
(18 x 3) + (36 x 8) = ? + 10
16 × 14 + 30 × 21 = 14 × ?
125 + 30% of 250 + √576 = ?
What will come in the place of question mark (?) in the given expression?
(308 – 154) ÷ 11 = ? ÷ 15
(-251 × 21 × -12) ÷ ? = 158.13
