Quantitative Reasoning - Partnership Problems

Partnership Problems

(Quantitative Reasoning)

There are two kinds of partnership:
⑴ Simple Partnership
⑵ Compound Partnership

⑴ Simple Partnership
In this partnership, time remains the same in case of each partner.
Suppose A and B are two partners. A invests ₹p and B invests ₹q then,
Share of Partner A's profit/loss : Share of Partner's B profit/loss = p : q

⑵ Compound Partnership
In this case, time is different.
Suppose A and B are two partners. A invests ₹p for m months and B invests ₹q for n months then,
Share of Partner A's profit/loss : Share of Partner's B profit/loss = p×m : q×n

Maths - Percentage Problems

Percentage

Mathematical Reasoning

In percentage, a fraction is expressed in terms of hundred. Thus, per cent is a fraction whose denominator is 100.

The sign of 100 is %

Two Important Conventions:
① To convert a fraction or decimal into percent multiply it by 100. ∴ 20% = 20/100
② To convert per cent into a fraction or a decimal, divide by 100 and delete the % sign.
1/5 = (1/5) ✕ 100 = 20%


Question 1: Express 5/2 as rate percent.

Answer: (5/2) ✕ 100 = (5 ✕ 100)/ 2 = 500/2 = 250%


Question 2: Find 25% of 1000
