Simple Interest Mcq Pdf Model Questions & Answers, Practice Test for ssc chsl tier 1 2024

Answer: (a)

Amt = 45000$(1 + 9/100)^2$ = 53464.5

CI = 53464.5 – 45000 = 8464.5

Answer:(c)

Let A lent Rs. x and B lent Rs. y

Since, A and B together lent out Rs. 81600

∴ x + y = 81,600

Now, given (r) Rate = 4%

∴ 1 + r = 1 + $4/100 = 26/25$

According to the question, we have

$x/y = (26/25)^{3 – 2} = 26/25$

∴ Investment made by B = 81600 × $25/51$ = 40,000

Answer:(a)

Let the principal be P and rate of interest be R%.

∴ Required ratio = $[({P × R × 6}/100)/({P × R × 9}/100)] = {6PR}/{9PR} = 6/9 = 2 : 3$

Answer:(e)

S.I. = ${12000 × 9 × 13}/100$

= Rs. 14040

∴ Amount = 12000 + 14040

= Rs. 26040

Answer:(b)

Let amount invested at 12% be x and amount invested at 10% be y.

According to question

130 = ${x × 12 × 1}/100 + {y × 10 × 1}/100$

⇒ 13000 = 12x + 10 y …(1)

And 134 = ${x × 10 × 1}/100 + {y × 12 × 1}/100$

⇒ 13400 = 10x + 12y ... (2)

From equations (1) and (2)

x = 500
