A, B को 600 रु. 2 वर्षों के लिए एवं C की 150 रु. 4 वर्षों के लिए उधार देता है तथा \( A^{\prime} \) दोनों से एक साथ 90 रु. साधारण ब्यांज के रूप में प्राप्त करता है। ब्याज की दर ज्ञात करें। \( \begin{array}{ll}\text { (1) } 5 \% & \text { (2) } 3 \% \\ \text { (3) } 6 \% & \text { (4) } 7 \%\end{array} \)

121. A shopkeeper advertises for selling cloth at \( 4 \% \) loss. However, by using a false metre scale he actually gains \( 20 \% \). What is the actual length of the scale? \( \begin{array}{ll}\text { (R.R.B., } 2006 \text { ) } \\ \begin{array}{ll}\text { (a) } 70 \mathrm{~cm} & \text { (b) } 75 \mathrm{~cm} \\ \text { (c) } 80 \mathrm{~cm} & \text { (d) } 90 \mathrm{~cm}\end{array} \\ \text { 122. Instead of a metre scale, a cloth merchant uses a } \\ 120 \mathrm{~cm} \text { scale while buying but uses an } 80 \mathrm{~cm} \text { scale } \\ \text { while selling the same cloth. If he offers a discount } \\ \text { of } 20 \% \text { on cash payment what is his overall profit } \\ \text { percentage? } \\ \begin{array}{ll}\text { (a) } 15 \% & \text { (b) } 20 \% \\ \text { (c) } 25 \% & \text { (d) } 40 \%\end{array} \\ \text { gain percentage but actually earns } 37 \frac{1}{2} \% \text { profit by } \\ \text { using false weight. If for a kg he uses a weight of } \\ 800 \text { gm, what is the nominal gain percentage at } \\ \text { which he claims to be selling his goods? } \\ \begin{array}{ll}\text { (a) } 8 \% & \text { (b) } 10 \% \\ \text { (c) } 15 \% & \text { (d) } 20 \%\end{array}\end{array} \).
